Explanation / Answer

Q.27

Answer: Option A

Explanation: Pulmonary circuit has a lower blood pressure when compared to that of systemic circuit. The blood pressure of pulmonary circuit is 25/8 mmHg and the systemic circuit has about 120/80 mmHg. Pulmonary circuit has lower overall resistance, this facilitates higher blood flow volume per unit.
