Title: How many liters of blood are distributed between the pulmonary and systemic circ Post by: ppk on Jul 24, 2011 How many liters of blood are distributed between the pulmonary and systemic circuits in a "typical" person? Assume 20% of the blood is in the lungs at any moment. If the cardiac output is 5 L/min, how long will it take a drop of blood to flow from the right ventricle to the left ventricle?

There are about 5 liters of blood in a 70 kg man. If 20% of the blood is in the lungs, then 5 × 0.2 = 1 liter of blood in the lungs. 1 L × 1 min/5 L × 60 sec/1 min × 1 min/60 sec = 12 seconds. Hope this helps... |
