The circulatory system transports nutrients, water, and oxygen to cells throughout the body and removes waste such as carbon dioxide. It is divided into three main parts: the heart, blood vessels, and blood. The heart pumps blood through blood vessels, including arteries and veins, and blood carries oxygen, nutrients, waste, white blood cells, and platelets.
