Circulatory System Review

Front

What is the primary function of the left ventricle in the circulatory system?

Back

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

Front

What do arteries do in the circulatory system?

Back

Arteries carry oxygenated blood away from the heart to the tissues of the body.

Front

What gas is removed from the blood as it reaches the lungs?

Back

Carbon dioxide is removed from the blood in the lungs.

Front

What are capillaries and what is their role in the circulatory system?

Back

Capillaries are the smallest blood vessels that facilitate the exchange of oxygen, carbon dioxide, nutrients, and waste between blood and tissues.

Front

What structure does the left atrium receive blood from?

Back

The left atrium receives oxygenated blood from the pulmonary veins.

Front

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

Back

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

Front

What is the difference between arteries and veins?

Back

Arteries carry oxygenated blood away from the heart, while veins carry deoxygenated blood back to the heart.

Front

What is the significance of the aorta in the circulatory system?

Back

The aorta is the largest artery in the body and is responsible for distributing oxygenated blood from the heart to the rest of the body.

Front

What is the function of the pulmonary arteries?

Back

Pulmonary arteries carry deoxygenated blood from the right ventricle to the lungs.

Front

What is the role of the valves in the heart?

Back

Valves prevent the backflow of blood and ensure it flows in one direction through the heart chambers.
