Sheep Heart review

Front

What is the function of the pulmonary semilunar valve?

Back

The pulmonary semilunar valve prevents backflow of blood from the pulmonary artery into the right ventricle after it has been pumped out.

Front

What are coronary blood vessels?

Back

Coronary blood vessels supply blood to the heart muscle itself, providing it with oxygen and nutrients.

Front

What is the role of the right ventricle?

Back

The right ventricle pumps deoxygenated blood to the lungs for oxygenation.

Front

What is the interventricular sulcus?

Back

The interventricular sulcus is a groove that separates the left and right ventricles of the heart.

Front

What is the function of the aortic semilunar valve?

Back

The aortic semilunar valve prevents backflow of blood from the aorta into the left ventricle after it has been pumped out.

Front

What is the structure of the heart?

Back

The heart consists of four chambers: two atria (upper chambers) and two ventricles (lower chambers).

Front

What is the significance of the chordae tendinae?

Back

Chordae tendinae are fibrous cords that connect the papillary muscles to the heart valves, preventing the valves from inverting.

Front

What is the apex of the heart?

Back

The apex is the pointed tip of the heart, located at the bottom of the left ventricle.

Front

What is the difference between the left and right ventricles?

Back

The left ventricle pumps oxygenated blood to the body, while the right ventricle pumps deoxygenated blood to the lungs.

Front

What is the function of the papillary muscles?

Back

Papillary muscles contract to help open and close the heart valves during the cardiac cycle.
