Question

Why do we pass more urine during the winter and wet season?
(a) Increased secretion of ADH
(b) Increased activity of kidneys
(c) Decreased absorption of nephrons
(d) Reduced sweating

Answer 1

Hint: Urine is the metabolic byproduct that consists of excess water, minerals, and toxins.

Complete answer: During the winter season, the surrounding temperature is very low. So there is less sweating, thus no evaporation losses. Due to this reason, we pass more urine during the winter and wet season.

Additional information:
During the winter season, to keep the body temperature constant, the blood capillaries in the skin get constricted and the blood pressure is increased resulting in our body getting warmed up. To maintain the normal blood pressure, the excess water along with the wastes is excreted mostly in the form of urine.

During summer the surrounding temperature is high hence we lose water in the form of sweat, direct evaporation considerably. Hence kidneys absorb water for maintaining the water balance of the blood and less urine is formed resulting in less frequent urination.

So, the correct answer is ‘Reduced sweating’.

Note:
The hormones secreted by the adrenal gland play an important role in balancing water levels in the body by sending signals to kidneys. Kidneys determine the necessity for water intake by creating a feeling of thirstiness. Kidneys also maintain the balance of water content in the body by controlling the amount of water to absorb and release.
