Front

What is the main function of the left ventricle in the heart?

Back

The left ventricle pumps oxygen-rich blood to all parts of the body.

Front

What structure in the heart prevents the mixing of oxygen-rich and oxygen-poor blood?

Back

The septum separates the left and right sides of the heart.

Front

What does the left atrium do in the circulatory system?

Back

The left atrium receives oxygen-rich blood from the lungs.

Front

Describe the flow of blood from the atria to the ventricles.

Back

Blood passes from the atria to the ventricles during the cardiac cycle.

Front

What is the role of the pulmonary artery?

Back

The pulmonary artery carries oxygen-poor blood from the right ventricle to the lungs.

Front

What is the significance of the septum in the heart?

Back

The septum prevents the mixing of oxygen-rich and oxygen-poor blood.

Front

Identify the main chambers of the heart involved in systemic circulation.

Back

The left atrium and left ventricle are involved in systemic circulation.

Front

What is the function of the right atrium?

Back

The right atrium receives oxygen-poor blood from the body.

Front

How does blood flow through the heart during one complete heartbeat?

Back

Blood flows from the body into the right atrium, then to the right ventricle, to the lungs, back to the left atrium, and finally to the left ventricle before being pumped to the body.

Front

What is the role of valves in the heart?

Back

Valves ensure unidirectional blood flow through the heart chambers.
