Front

What is the pathway of blood after it leaves the right atrium?

Back

After leaving the right atrium, blood flows into the right ventricle.

Front

Where does blood go after it gets oxygen from the lungs?

Back

After getting oxygen from the lungs, blood returns to the left atrium through the pulmonary veins.

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 are the main components of the circulatory system?

Back

The main components of the circulatory system are the heart, blood vessels (arteries, veins, capillaries), and blood.

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 heart, while deoxygenated blood is low in oxygen and is carried from the body back to the heart.

Front

What is the function of the left ventricle?

Back

The left ventricle pumps oxygenated blood into the aorta, distributing it to the rest of the body.

Front

What is the significance of the pulmonary veins?

Back

The pulmonary veins carry oxygenated blood from the lungs to the left atrium of the heart.

Front

What happens to blood in the lungs?

Back

In the lungs, blood releases carbon dioxide and absorbs oxygen during the process of respiration.
