Detailed explanation-1: -The systemic circulation provides the functional blood supply to all body tissue. It carries oxygen and nutrients to the cells and picks up carbon dioxide and waste products. Systemic circulation carries oxygenated blood from the left ventricle, through the arteries, to the capillaries in the tissues of the body.
Detailed explanation-2: -The lung also has a systemic vascular supply, the bronchial circulation, which provides oxygenated blood from the systemic circulation to the walls of the conducting airways, pulmonary arteries and veins.
Detailed explanation-3: -Systemic circulation includes blood flow to all parts of the body except the lungs. Both veins and arteries contain semilunar valves. The walls of veins are much thinner than arteries. Under abnormal conditions, the AV node or the Purkinje fibers may act as ectopic pacemakers.
