The heart is the most important organ in the body aside from the brain. It provides the body with much needed blood. The heart has many functions to perform and undertake if it is to provide and support the lifeform that it is within. The major function of the heart is pumping oxygenated blood around the body in order for the body to work to its highest ability. In order for the muscles in the body to function properly, blood is needed. The heart pumps blood to all the important areas throughout the body through an artery known as the aorta (which is the main artery which leads from the body). A thick layer of muscle called the septum which separates both sides of the heart. The deoxygenated blood exits through the right ventricle of the heart…show more content…
When you exercise at a very hard rate your heart begins to beat faster as you increase the amount of exercise. As your exercise you use a lot of oxygen which makes your heart and lungs work harder and faster. The lungs work harder and become stronger during exercise and your heart works at a faster rate to pump blood throughout the body to the muscles that are being…show more content…
The right ventricles only function is to pump blood into pulmonary circulation for the lungs, while the left ventricle pumps blood throughout the whole of the of the body.
Describe the structure and function of the different valves within the heart:
Tricuspid valve: This is found in-between the right atrium and the right ventricle.
Pulmonary valve: This is found in-between the right ventricle and the pulmonary artery.
Mitral valve: This is found in-between the left atrium and the left ventricle.
Aortic valve: This is found in-between the left ventricle and the aorta
The left atrium tightens and relaxes which allows for more blood to enter the left ventricle. As the heart muscle tenses and relaxes, it allows for blood to flow into the ventricles, atria and various times. Allowing a full intake and out-take of blood.

What is special about the pulmonary artery and vein? Why?
The veins around the body generally transport deoxygenated blood from places in the body back to the heart, however, the pulmonary vein is one of the few veins that hold and transport oxygenated blood through the body. However, the pulmonary artery carries deoxygenated blood, and the pulmonary vein transports oxygenated blood.
