MEDICAL PHYSIOLOGY

Detailed explanation-1: -The left ventricle is an integral part of the cardiovascular system. Left ventricular contraction forces oxygenated blood through the aortic valve to be distributed to the entire body. With such an important role, decreased function caused by injury or maladaptive change can induce symptoms of the disease.

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 systemic circuit is that part of your circulatory system that carries blood away from your heart, delivers it to most of your organs and tissues, and returns it to your heart again. The systemic circuit is distinct from the pulmonary circuit, which only conducts blood between your heart and lungs.

Detailed explanation-4: -In the systemic circulation, the left ventricle pumps oxygen-rich blood into the main artery (aorta). The blood travels from the main artery to larger and smaller arteries and into the capillary network.
