The heart is one of the most important organs in the human body. The heart continuously pumps blood throughout your body through blood vessels. The system of blood vessels is over 60,000 miles long. You can find your heart in your chest and it is protected by the rib cage. The human heart has four chambers; the right atrium, left atrium, right ventricle, and left ventricle. There are also four valves in the heart; they make sure blood only goes one way, in or out. The flow of blood through the heart follows a path to make sure that oxygenated blood from the lungs travels through major arteries and gets carried to body tissues. Carbon dioxide and oxygen travels to and from tiny air sacs in the lungs, through the walls…show more content…
Blood then flows from your right atrium into your right ventricle through the open tricuspid valve. The tricuspid valve shuts when the ventricles are full. It shuts to prevent the blood from flowing backward into the atria while the ventricle contracts. As the ventricle contracts, the blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs where it is oxygenated. On the left side of the heart, the pulmonary vein empties oxygen- rich blood, from the lungs into the left atrium. Next, the blood flows from your left atrium into your left ventricle through the open mitral valve. The mitral valve shuts when the ventricles are full, this prevents blood from going backward into the atria while the ventricles contract. Then the blood leaves the heart through the aortic valve, into the aorta and to the body. This process is repeated, causing blood to flow continuously to the heart, lungs, and body. The process happens about 72-80 times a minute and pumping approximately 2,000 gallons of blood every day. Even though there is a left and right side of the heart all of this is happening at the same Oxygenated blood leaves the left ventricle. This blood flows to the
