About the amount of blood flow through kidneys in one hour

Introduction:

The excretory system is the system of an organism's body that performs the function of excretion, the bodily process of discharging wastes. Several parts of the body are involved in this process, such as sweat glands, the liver, the lungs and the kidney system. The kidneys maintain homeostasis by removing wastes and excess water from the body and by maintaining the pH of the blood. The kidneys are the major excretory organ in the body. It is a bean-shaped organ that is involved in urine formation performs filtration of blood.

Explanation of Solution

Each kidney filters about 180 L of blood each day in adults but produces only about 1.5 L of urine. Approximately 350 liters of blood pass in a single day, so divide 350 liters by 24 which is about 14.5 liters an hour.

Conclusion

14.5 liters of blood flow through kidneys in one hour.
