layer closet to the heart

outer layer

fluid-filled cavity between the pericardial layers

lower right and left chambers of the heart

structures within the heart that open and close with the heartbeat to regulate the one-way flow of blood

heart valve between the left ventricle and the aorta

heart valve between the left atrium and left ventricle

heart valve opening from the right ventricle to the pulmonary artery

vavle between the right atrium and the right ventricle

valves located at intervals within the liniing of veins, especially in the legs, which constrict with muscle action to move the blood returning to the heart

vessels that carry blood from the heart to the arterioles

large artery that is the main trunk of the arterial system branching from the left ventricle

small vessels that receive blood from the arteries

tiny vessels that join arterioles and venules

small vessels that gather blood from the capillaries into the veins

vessels that carry blood to the heart from the venules

circulation of blood throughout the body via arteries, arterioles, capillaries, venules, and veins to deliver oxygen and nutrients to body tissues

circulation of blood through the coronary blood vessels to deliver oxygen and nutrients to the heart muscle tissues

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
