Cardiovascular

Question 1

What is the equation for cardiac output?

Answer 1

Cardiac Output = Stroke Volume x Heart rate

Question 2

What is the full order of blood flow through the heart?

Answer 2

1. Vena cava
2. Right atrium
3. Right ventricle
4. Pulmonary artery
5. Lungs
6. Pulmonary veins
7. Left atrium
8. Left ventricle
9. Aorta
10. Body

Question 3

What happens to deoxygenated blood when it enters the heart?

Answer 3

Deoxygenated blood enters the right atrium from the body.

The right atrium contracts, pushing blood into the right ventricle.

Question 4

What happens after the right ventricle receives blood?

Answer 4

The right ventricle contracts, pushing blood into the pulmonary artery.

The pulmonary artery carries blood to the lungs for gas exchange.

Question 5

What happens to oxygenated blood when it returns to the heart?

Answer 5

Oxygenated blood from the lungs is carried by the pulmonary veins into the left atrium.

The left atrium contracts, pushing blood into the left ventricle.

Question 6

What happens after the left ventricle receives blood?

Answer 6

The left ventricle contracts, pushing blood into the aorta.

The aorta carries oxygenated blood to the body.

Question 7

What are the two phases of the cardiac cycle and what do they do?

Answer 7

Diastole
when the chambers relax and fill with blood

Systole
when the chambers contract and eject blood
