What are the three components in the circulatory system?

Answer 1

Depending on the depth of your question, I would say

1) The Heart

2) Arteries

3) Veins

a little more in depth might say

1) Heart

2) Arteries & Veins

3) Capilleries

but I'd probably go with the first three (especially if you don't know what capilleries are).

Answer 2

Actually, four things make up the circulatory system. The heart (which pumps the blood), the veins (which distribute the blood through out you body), capillaries (which remove the oxygen from your blood and dispenses it to your cells), and the arteries (which takes unoxygenated blood back to the heart). However, since the respiratory system takes in the oxygen that is distributed, it might be considered a part of the circulatory system. The respiratory system is comprised of the mouth, wind pipe, trachea, lungs, diaphragm, and the alveoli or air sacs.
