Question
Chapter 25.4, Problem 13BYGO
Summary Introduction
To determine:
The reason for decrease in number of functional nephrons in old age.
The implications of this change for homeostasis and medication dosages.
Introduction:
The system in the body that performs the function of excretion of waste out of the body is termed as the excretory system. By this process homeostasis is maintained in the body, and hence, is highly important for humans. One of the important organs of excretory system is the kidney. The function of the kidney is to remove nitrogenous waste and toxins from the body via urine.
