Structure of the heartThe right half of our heart consists of blood coming from the vein, with a small amount of oxygen. This blood is pushed out through the heart through the pulmonary arteries into the lungs, where it assigns oxygen in the amount necessary for the body.

After the blood from the lungs is sent to the left side of the heart, and then the heart releases this blood through the aorta, and blood spreads throughout the body, thanks to a complex arterial system and capillaries.

Passing through the whole body, the blood saturates the tissues with air and nutrients through the capillaries, and carries away carbon dioxide and metabolic products. The blood goes through the veins in the right heart, and then along the circle.

How do the valves of the human heart.
The heart consists of four valves. Each valve is an opening that has the ability to flow blood in only one direction. The valve has two or three pieces of cloth, called flaps. The shutters serve to open the blood passage, and then close, so that it does not return back. In each department of the heart, the pressure level controls the opening and closing of the valves.

The tricus of the pedals of the valve is located in the right side of the heart, honey and the right ventricle of the heart. The pulmonary valve separates the right ventricle from the pulmonary arteries. The mitral valve in the left part of the heart, between the left atrium and the left ventricle, and the aortic valve divides the left ventricle and the aorta.
