Hint:The kidneys are the major excretory organ responsible for maintaining both the pH balance of the body, and getting rid of soluble wastes in urine. However, this is not the only way that our bodies lose water.
Complete answer:
Depending on the quantity of water taken in, and the kind of waste being excreted, the volume of urine will vary. For instance, it is very obvious that drinking more water will increase urine production. However, eating a lot of salt will also increase the amount of urine as sodium and chloride have high levels of hydration.
>Weather does not directly affect the functioning of the nephrons. They do not become less capable or reabsorbed in cooler and wet conditions. Option A is incorrect.
>The activity of the kidneys is also not regulated by changes in weather. Heat does not stimulate kidney function, nor does cold. Option B is also incorrect.
>When the weather is wet the temperatures are also cooler. During the Cold and the wet seasons, the amount of sweat produced by our bodies to keep us cool decreases greatly. This means that we are no longer losing water through sweat. This excess water has to be filtered out in some other way. Which is why the amount of urine produced goes up quite a bit. Option C is the correct answer.
>ADH secretion does regulate urine production. The more antidiuretic hormone released, the smaller the amount of urine produced and vice versa. However, the weather does not regulate ADH synthesis and release, therefore option D is incorrect.
Hence the correct answer is option ‘C’.
Note:Though such changes in weather do not affect kidney functioning, extreme heat can damage them. Beside damage caused by dehydration, extreme variations in temperature can directly affect glomerular function.
