Identify: depression on anterior surface of the heart - makes the division of left and right ventricles

Identify: (LIKELY A WORD QUESTION) a shallow depression in the interatrial septum that marks the spot where an opening, the foramen ovale, existed in the fetal heart.
Atrioventricular Valves
Valves located between the atrial and ventricular chambers on each side of the heart, prevent backflow into the atria when the ventricles are contracting.

Identify:

pulmonary and aortic valves located between the right ventricle and the pulmonary artery and between the left ventricle and the aorta

this allows oxygen-rich blood to pass from the left ventricle into the ascending aorta
Cusps
Identify: Valves are composed of two or three
Papillary Muscle
Identify: cone-like projections on the ventricular walls, to which the chordae tendineae are attached. The contraction of the papillary muscles and the tightening of the chordae tendineae prevent the valve flaps of the AV valves from turning inside out into the atria.
Fibrous Skeleton
Identify: four fibrous rings that surround the valve orifices and two triangular fibrous connections between these rings, the right and left fibrous trigones. The valves include the aortic and pulmonary semilunar valves and the right and left atrioventricular valves.

Identify: (NOTE, posterior view)
Small Cardiac Vein
Identify: vein that receives blood from the posterior surfaces of the right atrium and ventricle, in between great and middle
Small Cardiac Vein
Identify:
Superior Vena Cava
Identify: large vein that brings deoxygenated blood from the upper part of the body to the right atrium
Superior Vena Cava
Identify: receives blood from the head and arms and chest and empties into the right atrium of the heart
Inferior vena cava
Identify: receives blood from lower limbs and abdominal organs and empties into the posterior part of the right atrium of the heart
