Papillary muscle Muscle at the base of the chordae tendineae
Chordae tendineae Heart strings
Trabeculae carneae Fold of muscle in the ventricle
Endocardium Inner lining of the heart

Pulmonary (semilunar) valve Separates the right ventricle and the pulmonary artery
Pulmonary arteries (L & R )
Pulmonary veins (R & L) – posterior view
Mitral (bicuspid) valve
Aortic (semilunar) Valve Separates the left ventricle and the aorta Located behind the Mitral valve
Systemic Circulation Supplies oxygenated blood to all of the tissues located throughout the body, with the exception of the heart and lungs.
