Read the following statements A and B and choose the correct option.S...
Statement A: The principal nitrogenous waste in humans is synthesized in the liver.
Statement B: During summer when the body loses lots of water by evaporation, the release of ADH is suppressed.
Explanation:
Statement A: The principal nitrogenous waste in humans is synthesized in the liver.
The principal nitrogenous waste in humans is urea, which is synthesized in the liver. Urea is formed in the liver through a series of biochemical reactions known as the urea cycle. The urea cycle converts ammonia, a toxic byproduct of protein metabolism, into urea, which is less toxic and more easily excreted by the body. Urea is then transported to the kidneys for excretion.
Statement B: During summer when the body loses lots of water by evaporation, the release of ADH is suppressed.
ADH (antidiuretic hormone), also known as vasopressin, is a hormone released by the pituitary gland in response to dehydration or low blood volume. ADH acts on the kidneys to increase water reabsorption, reducing urine volume and conserving water in the body.
During summer, when the body loses lots of water by evaporation due to higher temperatures and increased sweating, the release of ADH is suppressed. This is because the body tries to maintain water balance by reducing water loss through urine. When the body is adequately hydrated, the release of ADH is inhibited, allowing for increased urine production and elimination of excess water. This mechanism helps to prevent water retention and maintain fluid balance in the body.
Conclusion:
Based on the explanations above, it can be concluded that only Statement A is correct. The principal nitrogenous waste in humans is synthesized in the liver, while Statement B is incorrect as the release of ADH is suppressed during dehydration or low blood volume, not specifically during summer.
Statement B: During summer when the body loses lots of water by evaporation, the release of ADH is suppressed.

Urea is synthesized within liver. Release of ADH increases during summer due to loss of more water by evaporation.
