Heart Structures and circulatory system notes Flashcardizz

Front

What is the function of the tricuspid valve?

Back

The tricuspid valve controls blood flow from the right atrium to the right ventricle.

Front

What are the ventricles of the heart?

Back

The ventricles are the bottom chambers of the heart that pump blood out to the lungs and the rest of the body.

Front

What are the atria?

Back

The atria are the thin-walled chambers of the heart that receive blood from the vena cava.

Front

What are chordae tendineae?

Back

Chordae tendineae are tendinous fibers that connect the atrioventricular valves (bicuspid and tricuspid) to the papillary muscles.

Front

What is the role of the aortic semilunar valve?

Back

The aortic semilunar valve guards the entrance to the ascending aorta, preventing backflow of blood into the left ventricle.

Front

What is the pulmonary semilunar valve?

Back

The pulmonary semilunar valve controls blood flow from the right ventricle to the pulmonary artery.

Front

What is the vena cava?

Back

The vena cava is a large vein that carries deoxygenated blood from the body back to the right atrium of the heart.

Front

What is the function of the heart valves?

Back

Heart valves ensure unidirectional blood flow through the heart chambers and prevent backflow.

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 interventricular septum?

Back

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