Which is the overall purpose of the excretory system? extracting energy from food maintaining homeostasis moving nutrients through the body gathering information

The overall purpose of excretory system is (B) homeostasis.

Further Explanation:

The excretion of body wastes is done by well-defined organ system known as the excretory system. Excretory system consists of two kidneys and the associated parts. The renal cortex, renal pelvis and medulla are the three parts of the kidney. The nephron is the smallest unit of the kidney. The skin, lungs and liver are the other excretory organs that are present in the human body. The major function of an excretory system is to eliminate the waste products like uric acid, ammonia and urea.

The process by which the maintenance of stability while adapting to the conditions that are considered to be optimal for survival occurs is known as homeostasis. The homeostasis in the body is maintained by the reabsorption of substances that are useful in the PCT and DCT.

Thus, the overall purpose of excretory system maintain the homeostasis of the body excretion of wastes from the body and reabsorption of useful substances into the body.
