what is the function of the cardiovascular system.?

Answer 1

to pump the blood throughout your body. Blood carries oxygen and carbon dioxide to and from cells. Each cell in your body needs oxygen (that's their food source) to survive and their waste product, carbon dioxide, needs to be excreted by you breathing out. That is why people w/ a heart attack need to be treated fast, b/c if you don't give oxygen to lets say an organ as important as the brain, you will expire.

Answer 2

The cardiovascular system is a combination of the heart and blood and your question cannot be answered with a single response. There are 3 functions of blood: A.) Transportation of oxygen, carbon dioxide, nutrients, minerals, vitamins, hormones & waste. B.) Regulation of pH, fluid balance & body temperature. C.) Protection against foreign organisms and against blood loss.

Functions of the heart include the cardiac cycle (systole & diastole), cardiac output, conduction & control of the heartrate.

I hope this isn't part of a school assignment.

Answer 3

The coronary circulation consists of the blood vessels that supply blood to, and remove blood from, the heart muscle itself. Although blood fills the chambers of the heart, the muscle tissue of the heart, or myocardium, is so thick that it requires coronary blood vessels to deliver blood deep into the myocardium. The vessels that supply blood high in oxygen to the myocardium are known as coronary arteries. The vessels that remove the deoxygenated blood from the heart muscle are known as cardiac veins.
The coronary arteries that run on the surface of the heart are called epicardial coronary arteries. These arteries, when healthy, are capable of autoregulation to maintain coronary blood flow at levels appropriate to the needs of the heart muscle. These relatively narrow vessels are commonly affected by atherosclerosis and can become blocked, causing angina or a heart attack. The coronary arteries are classified as "end circulation", since they represent the only source of blood supply to the myocardium: there is very little redundant blood supply, which is why blockage of these vessels can be so critical.

Answer 4

To circulate blood to the heart via the veins (they carry the dirty blood to the heart) The blood goes thru the ventricals (upper & lower) then is pumped thru the arteries (the clean oxyganated blood)
Broken down, to circulate the body with blood which nourishes the cells in the body. The lymph system is running nest to it and the impurities are picked up by the lymph as this happens.

Answer 5

Obviously you have never heard of the medical profession. Many parts of the human body do not function well or at all and the body still keeps chugging along. How does the organism KNOW that these vital cells must be replaced in order to avoid death? And now we bring in why we think you absurdly stupid - It does not KNOW any more than a rock KNOWS to fall down when you drop it.

Answer 6

I'm not sure but It's the heart system. and knowing that cardiovasucal means heart it probably refers to the heart and the system, (pumping the blood)?

Answer 7

an organ system which distributes the blood to deliver nutrients and remove wastes.short anwser.

Answer 8

It is to move nutrients though out your body and oxygen and help to expel waste. It also help to maintain your body temperature.

Answer 9

To keep you alive.

Answer 10

Breath in and out.....................pump blood throughout your body.
