The heart is situated inside the [[thorax]] in vertebrates and in the human body is slightly to the left. The human heart consists of 4 main chambers, 2 [[atria]] and 2 [[ventricle]]s. The right side of the heart receives blood from the body and pumps it to the lungs where it is oxygenated and returns to the left side of the heart. The left side of the heart pumps the oxygen-carrying blood to the rest of the body.
