ANAT Unit 8 Heart Anatomy Review

Front

What are the semilunar valves in the heart?

Back

The semilunar valves include the aortic valve and the pulmonary valve, which prevent backflow of blood into the ventricles after contraction.

Front

What is the interventricular septum?

Back

The interventricular septum is the muscular wall that separates the left and right ventricles of the heart.

Front

What is the function of the bicuspid valve?

Back

The bicuspid valve (or mitral valve) prevents backflow of blood from the left ventricle into the left atrium.

Front

What is the role of the left ventricle?

Back

The left ventricle pumps oxygenated blood into the aorta to supply the body.

Front

What prevents backflow of blood in the heart?

Back

Valves in the heart, including the atrioventricular and semilunar valves, prevent backflow of blood.

Front

What are the main functions of heart valves?

Back

Heart valves ensure unidirectional blood flow and prevent backflow during the cardiac cycle.

Front

What is the difference between the right and left atrium?

Back

The right atrium receives deoxygenated blood from the body, while the left atrium receives oxygenated blood from the lungs.

Front

What is the significance of the aortic semilunar valve?

Back

The aortic semilunar valve prevents backflow of blood from the aorta into the left ventricle.

Front

What is the pulmonary semilunar valve?

Back

The pulmonary semilunar valve prevents backflow of blood from the pulmonary artery into the right ventricle.

Front

What is the function of the vena cava?

Back

The vena cava are large veins that carry deoxygenated blood from the body back to the right atrium of the heart.
