The Heart

Front

What is the function of the tricuspid valve in the heart?

Back

The tricuspid valve prevents blood from flowing back into the right atrium from the right ventricle.

Front

What is the role of the pulmonary artery?

Back

The pulmonary artery carries deoxygenated blood from the right ventricle to the lungs for oxygenation.

Front

What structure does the arrow indicate in a diagram of the heart?

Back

The right atrium.

Front

True or False: The pulmonary artery carries oxygenated blood to the body.

Back

FALSE. The pulmonary artery carries deoxygenated blood to the lungs.

Front

What is the function of the superior vena cava?

Back

The superior vena cava carries deoxygenated blood from the upper body to the right atrium of the heart.

Front

What are the two main types of valves in the heart?

Back

The two main types of valves are atrioventricular valves (like the tricuspid and mitral valves) and semilunar valves (like the aortic and pulmonary valves).

Front

What is the significance of the right ventricle in the circulatory system?

Back

The right ventricle pumps deoxygenated blood into the pulmonary artery, leading to the lungs for oxygenation.

Front

What is the pathway of blood flow through the heart starting from the right atrium?

Back

Blood flows from the right atrium to the right ventricle, then to the pulmonary artery, and finally to the lungs.

Front

What is the difference between oxygenated and deoxygenated blood?

Back

Oxygenated blood is rich in oxygen and is carried from the lungs to the body, while deoxygenated blood is low in oxygen and is carried from the body to the lungs.

Front

What is the role of the left atrium in the heart?

Back

The left atrium receives oxygenated blood from the lungs via the pulmonary veins.
