Detailed explanation-1: -The heart is an organ about the size of your fist that pumps blood through your body. It is made up of multiple layers of tissue. Your heart is at the center of your circulatory system.
Detailed explanation-2: -The heart and lungs are located in the thorax, or chest cavity. The heart pumps blood from the body to the lungs, where the blood is oxygenated. It then returns the blood to the heart, which pumps the freshly oxygenated blood to the rest of the body.
