A Trip Through the Heart By Jennifer Kenny

---

¹     The heart is a muscle in the body that squeezes itself to send blood through the body's blood vessels. The heart works very hard but it never tires. It can also change how fast it pumps to meet the body's needs.
 
²     The heart is actually made of two pumps working side by side. Each pump has a small upper chamber called an atrium. Blood flows into the atrium from the vena cava (the main vein) or the pulmonary vein.
 
³     The ventricle is located below the atrium. It is larger than the atrium. It is the heart's main pumping chamber. It squeezes hard during each heartbeat, causing the blood inside it to move into the aorta (the main artery) or the pulmonary artery. From the aorta, the blood is sent around the body. From the pulmonary artery, the blood is sent to the lungs.
