What is the pressure as blood enters the right atrium? CORRECT ANSWERS: 5mmHg What organ system in the body acts on the blood in the vessels to make a pressure of 5mmHg? CORRECT ANSWERS: Deep skeletal muscle pump system What pressure is the blood under as it goes from the RA through the tricuspid valve? CORRECT ANSWERS: 5mmHg The bigger the diameter of the valve the __________ pressure is needed to move blood across it. CORRECT ANSWERS: Less The smaller the diameter of the valve the _________ pressure is needed to move blood across it. CORRECT ANSWERS: more What is the largest valve in the heart? CORRECT ANSWERS: tricuspid valve What is the normal right ventricular systolic pressure? CORRECT ANSWERS: 25mmHg How much smaller is the pulmonic valve than the tricuspid valve? CORRECT ANSWERS: 5x smaller. It takes 5mmHg to get across the tricuspid valve and 25mmHg to get across the pulmonic valve. Which valve has a bigger diameter, the tricuspid or pulmonic valve? CORRECT ANSWERS: Tricuspid Which valve requires more pressure to move across it, the tricuspid or the pulmonic? CORRECT ANSWERS: pulmonic Valve A requires 5mmHg to move blood and valve B requires 30mmHg. Which valve has a smaller diameter? CORRECT ANSWERS: Valve B What is the right ventricular diastolic pressure? CORRECT ANSWERS: 5mmHg What is the RV EDP? CORRECT ANSWERS: 5mmHg Why is the RV EDP not zero? CORRECT ANSWERS: Because some blood is not ejected out. The heart is not a perfectly efficient pump. What is a normal RV ejection fraction? CORRECT ANSWERS: 55-60% What is EDP? CORRECT ANSWERS: End Diastolic P
