Detailed explanation-1: -When the left ventricle contracts, it forces blood through the aortic semilunar valve and into the aorta. The aorta and its branches carries the blood to all the body’s tissues.
Detailed explanation-2: -The right ventricle pumps the oxygen-poor blood through the pulmonary valve to the lungs. The left atrium receives oxygen-rich blood from the lungs and pumps it through the mitral valve to the left ventricle. The left ventricle pumps the oxygen-rich blood through the aortic valve out to the rest of the body.
Detailed explanation-3: -The heart is divided into a right and left side, separated by a septum. Each side has an atrium (which receives blood as it enters) and a ventricle (from which blood is pumped out).
