Cardiac Cycle

Q.

Name the artery that carries deoxygenated blood from the heart to the lungs?

1. Renal artery

2. Pulmonary artery

3. Hepatic artery

4. Aorta

Q.

What are the 5 stages of the cardiac cycle?

Q. Which feature differentiates cardiac muscles from smooth muscles?

1. Presence of striations
2. Uninucleate cells
3. Involuntary
4. Do not get tired easily

Q. If the systolic pressure is 120 mm Hg and diastolic pressure is 80 mm Hg, the pulse pressure is

1. 120 - 80 = 40mm Hg
2. 120 /80 = 1.5 mm Hg
3. 120 * 80 = 9600 mm Hg
4. 120 + 80 = 200 mm Hg
