Q. Which statement about blood flow is FALSE? (Solved)
1. cardiac output = stroke volume x heart rate
2. the volume of blood pumped through the lungs equals the volume entering the heart
3. Poiseville’s Law predicts the effects of pressure and resistance on cardiac output
4. the resistance of the systemic circulation is 5 to 10 times the pulmonary vascular resistance
5. with constant pressure, a vessel with radius ‘2X ‘ has 16 times the flow of vessel with radius ‘X’
- b. the volume of blood pumped through the lungs equals the volume entering the heart
