4. Heart Chambers and Valves
Pulmonary Trunk
Pulmonary Arteries
Pulmonary Valve (pulmonary semilunar valve)
Pulmonary Veins
Bicuspid Valve (mitral valve)
Aorta
Aortic Valve (aortic semilunar valve)

6. Skeleton of the Heart
Fibrous rings with other masses of dense connective tissue found in part of the septum between the ventricles that make the skeleton of the heart.
Provide firm attachments for the heart valves
Prevents the outlets of the atria and ventricles from dilating during contraction.
