Answer:

As the heart beats, it pumps blood through a system of blood vessels, called the circulatory system. The vessels are elastic, muscular tubes that carry blood to every part of the body. The right and left sides of the heart work together. The pattern described below is repeated over and over, causing blood to flow continuously to the heart, lungs, and body.  Right Side of the Heart

, Blood enters the heart through two large veins, into the right atrium of the heart.  As the atrium contracts, blood flows from your right atrium into your right ventricle through the open valve.  When the ventricle is full, the valve shuts. This prevents blood from flowing backward into the atria while the ventricle contracts.  As the ventricle contracts, blood leaves the heart through the valve, into the pulmonary artery and to the lungs, where it is oxygenated and then returns to the left atrium through the pulmonary veins.

Left Side of the Heart

,The pulmonary veins empty oxygen-rich blood from the lungs into the left atrium of the heart.  As the atrium contracts, blood flows from your left atrium into your left ventricle through the open valve.  When the ventricle is full, the valve shuts. This prevents blood from flowing backward into the atrium while the ventricle contracts.  As the ventricle contracts, blood leaves the heart through the aortic valve, into the aorta and to the body.
