ANATOMY

Detailed explanation-1: -The main function of the circulatory system is to provide oxygen, nutrients and hormones to muscles, tissues and organs throughout your body. Another part of the circulatory system is to remove waste from cells and organs so your body can dispose of it.

Detailed explanation-2: -In general, arteries carry blood away from the heart and veins carry blood back to the heart. The cardiovascular system delivers oxygen, nutrients, hormones, and other important substances to cells and organs in the body. It plays an important role in helping the body meet the demands of activity, exercise, and stress.

Detailed explanation-3: -Circulates OXYGEN and removes Carbon Dioxide. Provides cells with NUTRIENTS. Removes the waste products of metabolism to the excretory organs for disposal.

Detailed explanation-4: -As cells use the oxygen and nutrients delivered by the arteries they create waste products, such as carbon dioxide. The veins then pick up this waste and deliver it around the body for it to be disposed of and then deliver the deoxygenated blood back to the heart.

Detailed explanation-5: -The heart, blood and blood vessels work together to service the cells of the body. Using the network of arteries, veins and capillaries, blood carries carbon dioxide to the lungs (for exhalation) and picks up oxygen. From the small intestine, the blood gathers food nutrients and delivers them to every cell.
