The LV is a very important chamber that pumps blood through the aortic valve (12) and into the aorta (13). The aorta is the main artery of the body. It receives all the blood that the heart has pumped out and distributes it to the rest of the body.
hearts have 2 types of chambers: atria and ventricles. Atria are where blood enters the heart and ventricles pump the blood out of the heart. Hearts take in oxygen poor blood, â¦ pump it through the pulmonary circuit (lungs/gills) where it gets oxygenated, and then they pump it out to the rest of the body.
