Physicians commonly refer to the right atrium and right ventricle together as the right heart and to the left atrium and ventricle as the left heart. Normally with each beat the right ventricle pumps the same amount of blood into the lungs that the left ventricle pumps out into the body. The heart is divided into four main chambers: the two upper chambers are called the left and right Atrium and two lower chambers are called the right and left Ventricle.There is a thick wall of muscle separating the right side and the left side of the heart called the septum. The human heart is a muscular organ that provides a continuous blood circulation through the cardiac cycle and is one of the most vital organs in the human body.Human Heart Made by: Marian Flaviu Stan Mariana Both on 8th grade
