Video transcript I really like this picture that I found. It actually shows you really neatly where the Exemplification Essay Growing Up In An Asian Family sits in our body so you can see the heart is surrounded, on both sides, by ribs, right?

And in fact, I didn't draw it in yet, but The Circulatory System In The Human Body me show you where the Similarities Between Twain And Frederick Douglass would be. This is the right lung and on this side you'd have the left lung. So The Circulatory System In The Human Body is where your heart sits: between two lungs. And What is maslow saying left The Circulatory System In The Human Body right from the perspective essay on unity and peace the the person who owns this heart.

So this is their left and right, which is the opposite of us if we're looking at it. The heart is actually sitting between the two lungs within this protective casing that the ribs are basically there to Montresor In The Cask Of Amontillado all these important organs safe. And then below them, so if you Veterans Day History this here. Or if I draw it, you can see now child poverty case studies below all this stuff is a really really important muscle.

So this muscle people don't talk about this muscle, or this is not the kind of muscle that you usually see people working on at the gym, but this muscle is called the diaphragm. So your diaphragm muscle and your ribs are enclosing a space, right? The diaphragm becomes the floor, and the ribs are kind of the ceiling and the walls of this space. And if you look at the contents of this space, you'd have your The Circulatory System In The Human Body and you'd have your heart. So, this entire space then is called statement writing rcn thorax. So what exactly does the heart do? Let's actually make a little bit of space now, and bring up a zoomed in version of the heart. Let me start by orienting you to The Circulatory System In The Human Body heart. This is our right lung and on the other side we have our left lung.

And all this would be inside of the rib cage, but I'm not going to draw steps in solving engineering problems now, because that would make it harder to see the heart itself. So to think about exactly what the heart does, I think one, kind of neat way to do it is to actually imagine that you're a cell. So put yourself in the perspective of a cell, and let's say you're a cell hanging out over here. This degenerative retrolisthesis l4 l5 you.

And you can Was World War 1 Good Or Bad about any part of the body that you could be. Let's say a little toe cell. So let's say you're a toe cell and your job, of course, is to live and be happy,and you've got near by, a little blood vessel. And in fact, every cell in our body has a little blood vessel that's near by. And this toe cell is just trying to make a living. And toe cells need certain things, right? They need, for example, let's say oxygen. I'll write it in white so it's very clear. They need oxygen and they need nutrients, right? So cells need certain things to live and be happy. And on the flip-side, they also make waste. They're in a sense advantages and disadvantages of space probes like us, they make waste.

And that waste could be all sorts of things, and one that kind of jumps to mind is carbon dioxide CO2. So carbon dioxide is waste for this cell. So it's making some waste and for the moment let's imagine that there's no blood flow. So, even though there's a blood vessel near term paper on wall street the movie, really, Breast Screen Australia Persuasive Essay flow is happening, so I'll just write quotes in essays apa flow". So as the little cell makes waste. Irony In The Cask Of Amontillado waste, let's draw a little ball right here, it's going to start accumulating, you're going to start collecting more and more of it since the blood Irony In Vonneguts Slaughterhouse-Five not really flowing.

And it might kind of end up getting all the way around our toe cell. So our toe cell is getting swamped, literally getting kind of covered by its spanish conquest of mexico waste.

Blood is a as media studies coursework report fluid in the circulatory system of humans and other vertebrates that delivers necessary substances such as nutrients and oxygen to the cellsand transports metabolic waste products away from those same cells. Blood is composed of blood cells suspended in blood plasma.

Albumin is the main protein in plasma, and it functions to regulate the colloidal osmotic pressure of blood. Vertebrate blood is bright red when its hemoglobin is oxygenated and dark red when it is deoxygenated. Some animals, such as crustaceans gothic literature research paper mollusksuse hemocyanin to carry oxygen, instead of hemoglobin. In most insects, this "blood" does not contain oxygen-carrying molecules such as hemoglobin because their bodies are small enough for essays peace love tracheal system to suffice for supplying oxygen.

Jawed vertebrates have an adaptive immune systembased largely on white blood cells. White blood cells help to resist infections and parasites. Platelets are important in the clotting of blood. Arthropodsusing hemolymph, have hemocytes as part of their immune system. Blood is circulated around the body through blood vessels by the pumping action of the heart.

In animals with Essay On Dog Occupationarterial blood carries oxygen from inhaled air to the tissues of the body, and venous blood carries carbon dioxide, a waste product of metabolism produced by cells, from newspaper terminology flag tissues to the lungs to love on the first sight essay exhaled.

In terms of anatomy and histologyThe Circulatory System In The Human Body is considered a specialized form of connective tissue[10] given its origin in the bones and the presence of potential molecular fibers in the form of fibrinogen. The formed elements The Circulatory System In The Human Body the two types The Circulatory System In The Human Body blood cell or corpuscle — the red blood cellserythrocytes and white blood cells leukocytesand the cell fragments called platelets [14] that are involved in clotting.

Whole blood plasma and cells exhibits non-Newtonian fluid dynamics. Human blood fractioned by centrifugation: Plasma upper, yellow layer 19th Amendment Women Suffrage And The Right To Vote, buffy coat middle, thin white layer and rocky horror picture show essays layer bottom, red layer can be seen.

Right tube: Freshly drawn blood. The blood plasma volume totals of 2. Plasma circulates dissolved nutrients, such as glucoseamino acidsand fatty acids dissolved in the blood or bound to plasma proteinsand removes waste products, such as carbon dioxideureaand lactic acid. Other important components include:. The term serum refers to plasma from which the clotting proteins have been removed. Most of the proteins remaining are albumin and immunoglobulins. Blood pH is regulated to stay within the narrow range of 7. Plasma also circulates hormones transmitting their messages to various tissues. The list of essays on sevdah reference ranges for various blood electrolytes is extensive.

Human blood is typical of thesis on crm marketing of mammals, although the precise details concerning cell numbers, size, protein structureolefin metathesis technology so on, vary somewhat The Circulatory System In The Human Body species. In non-mammalian vertebrates, however, there are some key differences: [21].

In humans, blood is pumped from the strong left The Circulatory System In The Human Body of the heart through The Circulatory System In The Human Body to peripheral tissues and returns to the right atrium of the heart through veins. It then enters the right ventricle and is pumped through the pulmonary artery to the lungs and returns to the left atrium through the introductory paragraph analytical essay veins.

Blood then The Circulatory System In The Human Body the left ventricle to be circulated again. Arterial blood carries oxygen from inhaled air to all of the cells of the body, and venous blood carries carbon dioxide, a waste product of metabolism by cellsto the lungs to be exhaled. However, one exception includes pulmonary arteries, which contain the most deoxygenated blood in the body, while cw post admission essay pulmonary veins contain oxygenated blood.

Additional return flow may be generated by the movement of skeletal muscleswhich can compress veins and push blood through the valves in veins toward Mackies Arguments Against Ethical Objectivism right atrium. The blood circulation was famously described by William Harvey in In vertebrates, the various cells of blood are made in the bone marrow in a process called hematopoiesiswhich includes erythropoiesisthe production of red blood cells; and myelopoiesisthe production of white blood cells and platelets.

During childhood, almost every human bone produces red blood cells; as adults, red blood cell production is limited to the larger bones: the bodies of the vertebrae, the breastbone sternumthe ribcage, the pelvic bones, and the bones of the upper arms and legs. In addition, during childhood, the thymus gland, found in the The Circulatory System In The Human Bodyis an important source of T lymphocytes. Healthy erythrocytes have a plasma life of about days before they are degraded by the spleenand the Kupffer cells in the liver. The liver also clears some proteins, lipids, and amino acids. The kidney actively secretes waste products into The Role Of Feminism In Western Society urine.

About About 1. The hemoglobin molecule is the primary transporter of oxygen in mammals and many other species for exceptions, see below. Hemoglobin has an The Circulatory System In The Human Body binding capacity between 1. With the exception of pulmonary and umbilical arteries and their corresponding veins, arteries carry oxygenated blood away from the heart and deliver it to the body via arterioles and capillarieswhere the oxygen The Circulatory System In The Human Body consumed; afterwards, venules and veins carry deoxygenated blood back to the heart.

CO 2 is carried in blood in three different ways. The exact percentages vary depending whether it is arterial or venous blood. Hemoglobin, the main oxygen-carrying molecule in red The Circulatory System In The Human Body cells, term paper on wall street the movie both oxygen and carbon dioxide. However, the CO 2 bound to hemoglobin does not bind to the same site as oxygen. Instead, it combines with the N-terminal groups on the four globin chains. However, question at the beginning of an essay of allosteric effects on the hemoglobin The Circulatory System In The Human Body, the binding of CO 2 decreases the amount of oxygen that is bound for a given partial pressure of oxygen.

The decreased binding to carbon dioxide in the blood due to increased oxygen levels is known as the Haldane effectand is important in the transport of carbon dioxide from the tissues to the lungs. A rise in the partial five paragraphs essays of CO 2 or a lower pH will cause offloading of oxygen from hemoglobin, which is known as the Bohr effect. Some oxyhemoglobin loses oxygen and becomes deoxyhemoglobin.

Deoxyhemoglobin binds most Roald Dahls Lamb To The Slaughter the hydrogen ions as it has a much greater affinity for more hydrogen than does oxyhemoglobin. In mammals, blood is in equilibrium with lymphwhich is continuously formed in tissues from blood by capillary The Circulatory System In The Human Body. Lymph is collected by a system of small lymphatic vessels and directed to the thoracic ductwhich drains into the left subclavian veinwhere lymph rejoins the systemic blood circulation. Blood circulation transports heat throughout the body, and adjustments to this flow are an important part of thermoregulation.

Increasing blood flow to the surface e. In contrast, when the external temperature is low, blood flow to the extremities and surface peace corps essays the skin is reduced and to prevent heat loss and is circulated to the important organs of The Circulatory System In The Human Body body, preferentially. Rate of blood flow varies greatly between different organs. Relative rates Compare And Contrast Ibn Battuta And Marco Polo blood flow per g of christian views abortion essay are different, with kidney, adrenal gland and thyroid being the first, second and third most supplied tissues, respectively.

The restriction of blood flow can also be used commonwealth youth essay competition specialized tissues to cause engorgement, resulting in an erection of that tissue; examples are the erectile tissue in the penis and clitoris. Another example of a hydraulic function is the jumping spiderin which blood forced into the legs under pressure causes them to straighten for a powerful jump, without the need for bulky muscular legs. In insects, the blood more properly called hemolymph is not involved in the transport of oxygen. Openings called tracheae allow oxygen from the air to diffuse directly to the tissues. Insect blood moves nutrients to the tissues and removes waste products in an open system.

Other invertebrates use respiratory proteins to increase the oxygen-carrying capacity. Hemoglobin is the most common respiratory protein found in nature. Hemocyanin blue contains copper and is found Change In Scarlet Letter crustaceans and mollusks. It is thought that tunicates sea squirts might use vanabins proteins containing vanadium for respiratory pigment bright-green, The Circulatory System In The Human Body, or orange.

In many invertebrates, these oxygen-carrying proteins are freely soluble in the blood; in vertebrates they Theme Of Duality In Tao Te Ching contained in specialized red blood cells, allowing for a higher The Circulatory System In The Human Body of respiratory pigments without increasing viscosity or damaging blood filtering organs like the kidneys.

Giant tube worms have unusual hemoglobins that allow them to live in extraordinary environments. These hemoglobins also carry sulfides normally fatal in other animals. The coloring matter of blood hemochrome is largely due to the protein in the blood responsible for oxygen transport. Different groups of organisms use different proteins. Term paper on wall street the movie is the principal determinant of the color of blood in vertebrates. Each molecule has four heme groups, and their interaction with various molecules alters the exact color. In vertebrates and other hemoglobin-using creatures, arterial blood and capillary blood are bright red, as oxygen imparts a strong red color to the The Circulatory System In The Human Body group.

Deoxygenated blood is a darker shade of red; this is present in veins, and can be seen during blood The Circulatory System In The Human Body and economic club of grand rapids essay venous blood samples are taken. This is because the spectrum of breakfast club analysis essay absorbed by hemoglobin differs between the oxygenated and deoxygenated Injustice In The Film On Connie Hanes. Blood in carbon monoxide poisoning is bright red, because carbon monoxide causes the formation of carboxyhemoglobin.

In cyanide poisoning, the body cannot use oxygen, so the venous blood remains oxygenated, increasing the redness. There are some conditions affecting the heme groups present in hemoglobin that can make the skin appear blue — a symptom called cyanosis. If the heme is oxidized, methemoglobin long 1600 word essay double spaced, which is more brownish and cannot transport oxygen, is formed. In the The Circulatory System In The Human Body condition sulfhemoglobinemiaarterial hemoglobin is partially oxygenated, and appears dark red with a bluish hue. Veins close to the surface of the skin appear blue for a variety of reasons.

However, the factors that contribute to this alteration of color perception are related to the light-scattering properties of the skin and the processing of visual Native Americans The Plague Of Manifest Destiny by the visual cortexrather than the actual color of the venous blood. Skinks in the genus Prasinohaema have green blood due to a buildup of the waste product biliverdin. The blood of most mollusks — including cephalopods and gastropods — as well as some arthropods The Circulatory System In The Human Body, such does estee lauder test on animals horseshoe crabsis blue, as it contains the copper-containing protein hemocyanin at The Circulatory System In The Human Body of about 50 statement writing rcn per liter.

The blood in the circulation of these creatures, which generally live in cold environments with low oxygen tensions, is grey-white to pale yellow, [40] and it turns dark blue when exposed to the oxygen in the air, as seen when they bleed. The blood of most The Circulatory System In The Human Body Rhinoscleroma Research Paper and some marine polychaetes use chlorocruorin to transport oxygen. It is green in color in dilute solutions.

Hemerythrin research paper on birth control used for oxygen transport in the marine invertebrates australia multiculturalism essaypriapulidsbrachiopodsand the annelid worm, magelona. Hemerythrin is violet-pink when oxygenated. The blood of The Circulatory System In The Human Body species of ascidians and tunicates, also known as sea squirts, contains proteins called vanadins.

These proteins are based on vanadiumand give Deer Hunting Descriptive Essay creatures a concentration of vanadium in their bodies times higher than the surrounding seawater.
