circulation of blood from the pulmonary artery through the vessels in the lungs and back to the heart via the pulmonary vein, providing for the exchange of gases
Coronary circulation
circulation of blood
Systemic circulation
circulation of blood throughout the body via arteries, arterioles, capillaries, venules, and veins to deliver oxygen and nutrients to body tissues
Veins
Vessels that carry blood to the heart from the venules
Capillaries
Tiny vessels that join arterioles and venules
Venules
Small vessels that recieve blood from the arteries
Capillaries
Tiny vessels that join arterioles and venules
Arterioles
Small vessels that recieve blood from the arteries
Aorta
Large artery that is the main trunk of the arterial system branching from the left ventricle
Arteries
Vessels that carry blood from the heart to the arterioles
Valves of the viens
Valves located at intervals within the lining of veins, especially in the legs, which constrict with muscle action to move the blood returning to the heart
Tricuspid Valve
Valve between the right atrium and the right ventricle
Pulmonary semilunar valve
Heart valve opening from the right ventricle to the pulmonary artery
Mitral Valve
Bicuspid Valve
Heart valve between the left atrium and the left ventricle
Aortic valve
Heart valve between the left ventricle and the aorta
Heart valves
Structures within the heart that open and close with the heartbeat to regulate the one-way flow of blood
Ventricle
Lower right or left chamber or heart
Parietal Pericardium
Fluid filled cavity between the pericardial layer
Visceral pericardium
Layer closest to the heart
Pericardium
Protective sac enclosing the heart composed of two layers with fluid between

Diastole
to expand; period during the cardiac cycle when blood enters the relaxed ventricles from the aorta
systole
to contract; period druing the cardiac cycle when the heart is in contraction and the blood is ejected through the aorta and the pulmonary artery
