Q. What is the valve that separates the aorta from the heart? What is the importance of that valve?
The valve between the aorta and the left ventricle is the aortic valve. The aortic valve prevents the retrograde flux of blood to the left ventricle during diastole, likewise, as the aortic valve closes during diastole a part of the retrograde blood flux is impelled through the coronary ostia (openings), orifices located in the aorta wall just after the valvular insertion and contiguous to the coronary circulation responsible for the blood supply of the cardiac tissues.
