Introduction: The kidney is an important organ of the excretory system. As the blood passes through the kidneys, it filters the nitrogenous wastes to form urine. It maintains the homeostasis of the body.

Answer to Problem 1TYU
Correct answer: The process that maintains homeostasis of body fluids by keeping them from becoming too dilute or too concentrated is osmoregulation.
Hence, the correct answer is option (c).
Explanation of Solution
Reason for the correct answer:
Osmoregulation is a biological process in which an organism regulates its osmotic pressure that eventually controls the water balance of the body. It is a part of homeostasis. Every organism has an osmoregulatory system that maintains the fluid balance in the body. The mammals maintain its osmotic balance by a specialized structure known as the kidney.
Option (c) is given as “osmoregulation”.
Osmoregulation is the process of controlling electrolytes (salt) and water in the body in order to maintain the body fluids in the homeostatic limits.
Hence, the correct answer is option (c).
Reasons for the incorrect answers:
Option (a) is given as “excretion”.
The process by which the
Hence, option (a) is incorrect.
Option (b) is given as “elimination”.
In the human body, elimination is not a defined physiological process. This process does not maintain the homeostasis of body fluids.
Hence, option (b) is incorrect.
Option (d) is given as “glomerular filtration”.
This process removes the waste products, ions, and excess water from the blood and returns the required molecules back into the blood. This process does not maintain the homeostasis of body fluids.
Hence, option (d) is incorrect.
Option (e) is given as “tubular secretion”.
Tubular secretion is the movement of substances from the blood into the tubular fluid. This process does not maintain the homeostasis of body fluids.
Hence, option (e) is incorrect.
Hence, options (a), (b), (d), and (e) are incorrect.
The process that maintains the homeostasis of body fluids is called osmoregulation.
