Cardiovascular System Test

Front

What is the function of the pulmonary artery?

Back

The pulmonary artery carries oxygen-poor blood from the heart to the lungs for oxygenation.

Front

What does depolarization of the heart indicate?

Back

Depolarization of the heart indicates that the heart muscle is contracting.

Front

How does oxygen-poor blood return to the heart from the body?

Back

Oxygen-poor blood returns to the heart via the superior and inferior vena cava.

Front

Which chamber of the heart is responsible for pumping oxygenated blood to the body?

Back

The left ventricle pumps oxygenated blood to the body.

Front

What is the pathway of an electrical impulse after it leaves the AV node?

Back

After leaving the AV node, the electrical impulse travels to the Bundle of His.

Front

What is the role of the aorta in the cardiovascular system?

Back

The aorta carries oxygen-rich blood from the heart to the rest of the body.

Front

What is the significance of the SA node in the heart?

Back

The SA node is the natural pacemaker of the heart, initiating the electrical impulses that regulate heartbeats.

Front

What is the difference between arteries and veins?

Back

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

Front

What is the function of the pulmonary veins?

Back

The pulmonary veins carry oxygen-rich blood from the lungs back to the heart.

Front

What is cardiac output?

Back

Cardiac output is the volume of blood the heart pumps per minute, calculated as heart rate multiplied by stroke volume.
