Upper chamber of the heart

Prevents blood movement from R. ventricle to R. atrium

Membranes around heart

Groove separating left and right ventricles

Prevents blood movement from L. ventricle to L. atrium

Inner lining of heart chamber

Layer largely composed of cardiac muscle tissue

Space containing serous fluid to reduce friction during heartbeats

Drains blood from myocardial capillaries

Supplies blood to heart muscle

Distributes blood to body organs except lungs

Groove separating atrial and ventricular portions of the heart

The visceral portion of the pericardium on the surface of the heart

Helps open and close the valve during contractions

Vein Artery

Blood flowMajor veins and arteries

• The first part of a heart sound, ____occurs during the ventricular_______, when the A-V valves are closing.

• The second part of a heart sound, ____occurs during ventricular ______, when the pulmonary and aortic valves are closing.

• The external structures of the heart include the ventricles, atria, arteries and veins. Arteries carry blood away from the heart while veins carry blood into the heart. The vessels colored blue indicate the transport of blood with relatively low content of oxygen and high content of carbon dioxide. The vessels colored red indicate the transport of blood with relatively high content of oxygen and low content of carbon dioxide.
