Sheep Heart review

Front

What is the function of the heart valves?

Back

The heart valves prevent the backflow of blood, ensuring it flows in one direction through the heart.

Front

What are the two main types of heart chambers?

Back

The two main types of heart chambers are atria (upper chambers) and ventricles (lower chambers).

Front

Which chamber of the heart is responsible for pumping blood to the lungs?

Back

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

Front

What is the role of the interventricular septum?

Back

The interventricular septum separates the left and right ventricles of the heart.

Front

What is the name of the valve that separates the right atrium from the right ventricle?

Back

The tricuspid valve separates the right atrium from the right ventricle.

Front

What is the name of the valve that separates the left atrium from the left ventricle?

Back

The bicuspid valve (or mitral valve) separates the left atrium from the left ventricle.

Front

What are chordae tendinae?

Back

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

Front

What is the purpose of the papillary muscles?

Back

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

Front

What is the difference between atria and ventricles in terms of size?

Back

Ventricles are larger than atria, as they need to generate more force to pump blood out of the heart.

Front

What is the pulmonary semilunar valve?

Back

The pulmonary semilunar valve is located between the right ventricle and the pulmonary artery, preventing backflow into the ventricle.
