Human's circulatory
The cardiovascular system consists of three things. The heart, blood vessels, and the blood. This system is powered by the heart. Nutrients, oxygen, and hormones are transported throughout the body through blood vessels. A healthy heart can beat from 60 to 100 times per minute.
There are two circulatory loops in humans: the pulmonary circulation loop and the systemic circulation loop. The pulmonary circulation loop moves deoxygenated blood from the heart to the lungs, where oxygen is added to the blood and it is returned back to the heart. The systemic circulation carries oxygenated blood from the heart to the tissues of the body, and then takes the deoxygenated blood back to the heart.
Blood vessels allow blood to flow quickly and efficiently from the heart to every region of the body and back again. There are three major types of blood vessels: arteries, capillaries and veins.
The purpose of the human circulatory system is to transport oxygen out to cells that need it, and also carry waste products like CO2 back to be exhaled.
