Question 1
What is the pressure as blood enters the right atrium?
CORRECT ANSWER
5mmHg
Question 2
What organ system in the body acts on the blood in the vessels to make a pressure of
5mmHg?
CORRECT ANSWER
Deep skeletal muscle pump system
Question 3
What pressure is the blood under as it goes from the RA through the tricuspid valve?
CORRECT ANSWER
5mmHg
Question 4
The bigger the diameter of the valve the __________ pressure is needed to move blood
across it.
CORRECT ANSWER
1

,Less
Question 5
The smaller the diameter of the valve the _________ pressure is needed to move blood
across it.
CORRECT ANSWER
more
Question 6
What is the largest valve in the heart?
CORRECT ANSWER
tricuspid valve
Question 7
What is the normal right ventricular systolic pressure?
CORRECT ANSWER
25mmHg
Question 8
How much smaller is the pulmonic valve than the tricuspid valve?
CORRECT ANSWER
5x smaller. It takes 5mmHg to get across the tricuspid valve and 25mmHg to get across the
pulmonic valve.

,Question 9
Which valve has a bigger diameter, the tricuspid or pulmonic valve?
CORRECT ANSWER
Tricuspid
Question 10
Which valve requires more pressure to move across it, the tricuspid or the pulmonic?
CORRECT ANSWER
pulmonic
Question 11
Valve A requires 5mmHg to move blood and valve B requires 30mmHg. Which valve has a
smaller diameter?
CORRECT ANSWER
Valve B
Question 12
What is the right ventricular diastolic pressure?
CORRECT ANSWER
5mmHg
Question 13
3
@THE STUDY VAULT
, What is the RV EDP?
CORRECT ANSWER
5mmHg
Question 14
Why is the RV EDP not zero?
CORRECT ANSWER
Because some blood is not ejected out. The heart is not a perfectly efficient pump.
Question 15
What is a normal RV ejection fraction?
CORRECT ANSWER
55-60%
Question 16
What is EDP?
CORRECT ANSWER
End Diastolic Pressure. An efficient heart has an ejection fraction of 55-60%, this leftover
blood in the ventricle is under a resting (diastolic) pressure.
Question 17
What is a normal diastolic pressure in the pulmonary artery?
CORRECT ANSWER
4
