see this gonna be a little long but u will know it only if u read it, k? \n there are 4 chambers in the human heart. the upper chambers are called atrium n the lower are called ventricles. there is a vertical partition called septum. the blood enters into the right atrium through two tube like veins called inferior n superior venacava. these venacavae carry De-oxygenated blood from the whole body.this blood which is in the atrium then goes to the right ventricle during the contraction of the atrium. at the same time blood enters the left atrium from a tube called pulmonary vein which comes from the lungs carrying oxygenated blood. when the atria contract ,this blood enters the left ventricle. when the ventricles contract the DE-oxygenated blood from the rt ventricle is pumped into pulmonary artery which goes to the lungs for oxygenation; and the oxygenated blood from the left ventricle is pumped throughout the body through the systemic aorta.

Circulatory - keeps the blood and nutrients circulating to all vital organs\nRespiratory - provides oxygen to the blood system, and eliminates CO2\nNeurological - controls the other systems\nDigestive - provides the nutrients circulated by the blood system, and excretes the waste products, ridding the body of toxins\nRenal - maintains healthy fluid balance so that the blood can flow through the body with ease, also eliminates waste products, ridding the body of toxins

The system of veins and arteries that moves (circulates) the blood around in your body.

1) OK\n2) B - Blood enters the right atrium and pass through right atrio-ventricular valve (tricuspid), then pulmonary valve, left atrio-ventricular valve (mitral) and aortic valve.\nhttp://www.guidant.com/condition/heart/heart_valves.shtml\n3) OK

The simple answer is that red blood cells take in oxygen (which is carried by haemoglobin) and release carbon dioxide.\nHowever, only a small amount of carbon dioxide is carried within red blood cells (combined with haemoglobin) - most carbon dioxide is transported in blood plasma.\nAlso, respiration within red blood cells is anaerobic and the waste product from this process is lactic acid (lactate) which is excreted from the cell.\nThe release of carbon dioxide from the red blood cells at the lungs is not exactly excretion.\nSo overall, the answer is that red blood cells take in oxygen and carbon dioxide, plus of course glucose (for respiration) and excrete lactic acid (lactate).

Blood is a liguid specially formulated to carry to every living cell of the body all the things essential to life - oxygen and other gases, iron and other minerals etc. It also helps to carry waste and toxins to organs that process them for disposal (lungs, liver, spleen etc). \n\nIn humans and the bigger animals its appearance is pretty obvious (red, gooey stuff), but in many small creatures and insects it is more mixed up with the general chemistry of the creature. They have less developed vascular systems (arteries and veins) and they don't process exactly the same chemicals as us so their 'blood' is a different colour and texture.\n\nFinally, even in humans there is more than one system for transporting stuff around - we also have our lymphatic system which contains a clear fluid called 'lymph'. It is vital in helping us to fight infections and when its working hard in our defence thats when you get swollen glands - these are the lymph nodes - factories for fighting the nasties transported there by the lymph - you have these all over, but especially in your throat, under your arms, in your groin etc. Its what the doctor feels for when you have a temperature.\n\nFascinating stuff!

The main system of transporting nutrients to the body's cells is through the blood stream. But once a nutrient arrives at a needy cell, it is still inside a blood vessel while the cell lies outside. The lack of nutrients inside the cell, and between the cell and the blood vessel, creates a concentration gradient between the blood vessel and the cell. Due to the lower concentration in the cell, the nutrient diffuses through the blood vessel wall and into the cell.

The right side of the heart is for pulmonary circulation. this is to take blood from the tissues rich in co2 and lower in Oxygen and circulate it thru the lungs. In the lungs the co2 is dumped off and a fresh load of oxygen is picked up by the hemoglobin in the red blood cell. The left side of the heart now gets this fresh blood and the left ventricle pumps blood thru the body but not the lungs. the right ventricle pumps blood thru the lungs.

The heart is what pumps blood throughout the body, keeping all organs functioning. Blood flows to the body through arteries and blood flows back to the heart through veins. Its all one big system - the circulatory system.

r.b.c is Red Blood Cell.Red blood cells perform the most important blood duty. A single drop of blood contains millions of red blood cells which are constantly traveling through your body delivering oxygen and removing waste. If they weren't, your body would slowly die.

YES , OUR BLOOD CONTAIN Hemoglobin or haemoglobin (frequently abbreviated as Hb) is the iron-containing oxygen-transport metalloprotein in the red cells of the blood in mammals and other animals. Hemoglobin transports oxygen from the lungs to the rest of the body, such as to the muscles, where it releases the oxygen load. IRON IS A CONDUCTOR OF ELECTRICITY

The circulatory system comprises all structures that relate to the circulation of blood throughout the body.  This includes the heart, the aorta (main artery coming out of the heart), the major organ arteries, the smaller branch arteries going into the organs, arterioles (even smaller branch arteries), capillaries (fine, almost microscopic vessels where oxygen and nutrients are delivered to the organ), venules (small veins that start the return of blood away from the organ), small veins, larger veins, inferior vean cava (main vein from the lower 2/3 of the body), superior vena cava (main vein from the upper 1/3 of the body), and finally the heart again.  The circulatory system is essentially a closed plumbing system, driven by the beating of the heart.

Through veins, artilleries and capillaries powered by the pumping motion of the heart. \n☆

The lymphatic system is a good answer as it filters the blood, easing the effort the immune system must make, as well as draining fluid so as to not overwork the circulatory system.  The hematopoietic system (which makes blood cells) also makes the primary components of both systems - white blood cells for the immune system, and all the cellular components on the bloodstream for the circulatory system.

blood pressure, force exerted by the blood upon the walls of the arteries. The pressure in the arteries originates in the pumping action of the heart, and pressure waves can be felt at the wrist and at other points where arteries lie near the surface of the body (see pulse). Since the heart can pump blood into the large arteries more quickly than it can be absorbed and released by the tiny arterioles and capillaries, considerable inner pressure always exists in the arteries. The contraction of the heart (systole) causes the blood pressure to rise to its highest point, and relaxation of the heart (diastole) brings the pressure down to its lowest point.\nBlood pressure is strongest in the aorta, where the blood leaves the heart. It diminishes progressively in the smaller blood vessels and reaches its lowest point in the veins (see circulatory system). Blood pressure manifests itself dramatically when an artery is severed or pierced and the blood (under pressure) ejects in spurts.
