How it Works Heart

How it Works Heart, Conceived of lifelong weight, blood will continue to circulate in the body. Blood returning from the lungs (Pulmonum) through the veins of the lungs (pulmonary) with a backup oxygen (oxygen) is updated into the foyer the left heart. When the contract left the porch, the blood is squeezed into the chamber through the mitral valve.

How it Works Heart, When the left ventricle contracts, the mitral valve is closed and the aortic valve opening. Blood is squeezed into the aorta. Then flowed through the arteries to the entire body. Sharing the acidic substance (oxygen) to tissues.

Then the blood back into the heart. Passing the right atrium of the large veins, from the bottom of the body and the head and upper body. Blood is squeezed into the right ventricle through alveolus tricuspid. When the right ventricle contracts, the tricuspid valve is closed. Blood is squeezed into the lung artery (pulmonary artery) through the pulmonary valve. In the lung tissue (alveoli) of blood oxygen reserves updated. To then go back to the porch behind the left through the pulmonary vessel. This process is repeated continuously with a frequency 75 times per minute.
