The volume of circulating blood in the human body is 1/13 of the body weight. The systemic circulation

The volume of circulating blood in the human body is 1/13 of the body weight. The systemic circulation contains 75-80 percent, and 20-25 percent of the blood in the small circle. How much blood circulates in the pulmonary circulation of a person weighing 65 kg?

Let’s find how much blood circulates in a human body weighing 65 kg in total:

65 * 1/13 = 5 liters;

Let’s find how much blood circulates in the pulmonary circulation:

5 * 0.2 = 1 liter;

5 * 0.25 = 1.25 liters.

Answer: 1-1.25 liters.

Explanation: Converting percentages to decimal. 20% = 0.2, 25% = 0.25.
