The cardiovascular system Organization Heart aA muscle pump to maintain the flow of blood a Consist of four chambers(right and left atria, right and left ventricles) Artery(a) carry blood away from the heart eins( v) carry blood back to the heart Capillary microscopic vessels, the area of exchange between blood and tissue fluid
The cardiovascular system Organization ◼ Heart ❑ A muscle pump to maintain the flow of blood ❑ Consist of four chambers (right and left atria, right and left ventricles) ◼ Artery (a.) carry blood away from the heart ◼ Veins ( v.) carry blood back to the heart ◼ Capillary microscopic vessels, the area of exchange between blood and tissue fluid
The cardiovascular system Blood circulation Systemic circulation left ventricle→→ aorta and its branches→ capillaries of body-superior and inferior vena cava right atrium Pulmonary circulation right ventricle-pulmonary a→ capillaries of lung→ pulmonary V. - left atrium
The cardiovascular system Blood circulation ◼ Systemic circulation left ventricle→aorta and its branches→capillaries of body→superior and inferior vena cava→right atrium ◼ Pulmonary circulation right ventricle→pulmonary a.→capillaries of lung → pulmonary v. →left atrium
