The heart is a muscle located in the chest that pumps blood through the circulatory system. It has four chambers and beats between 60-100 times per minute for adults. The circulatory system includes the heart, blood vessels, and blood. It transports blood through arteries and veins, and uses capillaries to exchange oxygen and nutrients to tissues before returning to the heart. The circulatory system helps regulate body processes and temperature.
