Anatomy and Physiology:
The cardiovascular system consists of the heart, the arteries, and the blood. The heart is a muscle organ that circulates blood by flexing and stretching its muscular walls. Blood that has been oxygen deprived is pumped from the body into the atria, where it is oxygenated before being pumped back out to the body.
The arteries, veins, and capillaries are the vessels that are responsible for carrying blood to and away from the heart. Blood that has been exposed to oxygen travels through arteries and returns to the heart through veins. To deliver oxygen, nutrients, and hormones to cells, the body relies on capillaries, the smallest
