Historical biological theories tend to describe that behaviors are inherited biological tendencies passed down through evolution, and contemporary biosocial theories are explained by saying that genes and other biological features are more facilitators of human behavior instead of determinants.
Like the heart, the LVAD is a pump. One end hooks up to the left ventricle -- that's the chamber of the heart that pumps blood out of the lungs and into the body. The other end hooks up to the aorta, the body's main artery. A tube passes from the device through the skin.
From there, blood is pumped out through the aortic valve into the aortic arch and onward to the rest of the body. The left ventricle is the thickest of the heartâs chambers and is responsible for pumping oxygenated blood to tissues all over the body. By contrast, the right ventricle solely pumps blood to the lungs. Various conditions may affect the left ventricle and interfere with its proper functioning.
