ANATOMY

Detailed explanation-1: -The cardiovascular system is made up of the heart and blood vessels. It circulates blood throughout the body. A healthy cardiovascular system is vital to supplying the body with oxygen and nutrients.

Detailed explanation-2: -The circulatory system is made up of blood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.

Detailed explanation-3: -The cardiovascular system (your heart and blood vessels) supplies your body’s organs with oxygen and nutrients so your organs can do their jobs. Your blood vessels also carry carbon dioxide and other waste away for disposal.

Detailed explanation-4: -Your heart pumps blood around the body all the time-about five litres (eight pints) of it-and this is called circulation. Your heart, blood and blood vessels together make up your cardiovascular system (or heart and circulatory system).

Detailed explanation-5: -Arteries. Blood vessels that carry oxygenated blood away from the heart to the body. Veins. Blood vessels that carry blood from the body back into the heart. Capillaries. Tiny blood vessels between arteries and veins that distribute oxygen-rich blood to the body.
