a. 10
b. 15
c. 20
d. 22

Answer 1

Approximately 20 percent of cardiac output in a normal 70-kg adult flows through the kidneys.

Step-by-step explanation:

The kidneys filter about 20 percent of the total cardiac output in a normal 70-kg adult. Cardiac output refers to the volume of blood pumped by the heart per minute. In a resting adult, the heart pumps about 5 liters of blood per minute, and approximately 20 percent or one liter enters the kidneys to be filtered. This means that roughly 20 percent of the cardiac output flows through the kidneys.
