      Hi again!

      Blood enters the heart following the pressure gradient created by the continuous, rhythmic beating of the heart itself. Blood enters the heart chamber through the big blood vessel located on the top left and right chamber of the heart..

      The heart is cool as it has four chambers (2 on the right and 2 on the left) that all work together to receive and pump blood around the body. Blood enters the heart in the upper right chamber (atrium) and at the same time the upper left chamber is emptied. The blood then moves from the atrium into the lower chambers (ventricles) and is kept there by valves between the two chambers that shut closed to keep the blood there. Then once full, the blood is pumped from the right ventricle to the lungs to put oxygen into the blood, and from the left ventricle all around the body.
