Compare the heart chamber, artery name, pressures and flow rates of blood in the systemic and pulmonary circuits. Explain the pressure differences.
What will be an ideal response?
Answer: The right ventricle pumps through the pulmonary artery to the lungs for the pulmonary circuit, while the left ventricle pumps through the aorta for the systemic circuit. Cardiac output is the same on both sides, about 5 liters/min for an average human. Pressures (both systolic and diastolic) are much higher on the systemic side. Pressures are lower in the pulmonary circuit due to the lower resistance to flow (lower total peripheral resistance in the pulmonary circuit). This is partly because blood as to go farther in the systemic circuit; also the systemic circuit must have higher pressures to work against gravity to pump blood up to the head.
