The heart is located under the rib cage, between the lungs and to the left of the sternum. It is made up of muscles that contract and pump blood to the body. The heart contains four chambers and is divided into the right and left side by the septum. The sides are divided into top chambers called the atria and bottom chambers called the ventricles. The heart beats 100,000 times a day, pumping 2,000 gallons of blood each day through the body���s circulatory system. The blood carries oxygen from the lungs and nutrients to the body���s tissues. Blood also takes carbon dioxide away from the tissues.
There are three main types of blood vessels. The arteries carry oxygen-rich blood away from the heart to other parts of the body. The capillaries are thin blood vessels that are connected to the arteries and veins. They allow things to pass back and forth from the organ���s cells. The veins take blood back to the heart. The blood carried by the veins is low in oxygen and high in waste content. Veins become larger as they near the heart.Learn more about Muscles
