The circulatory system carries nutrients and oxygen throughout the body via blood vessels and the heart. It is composed of the heart, blood, and blood vessels. The heart pumps blood through the vessels, allowing it to pick up oxygen and drop off waste. As it circulates, blood's pulse can be felt and its rate changes with activity level or rest.
