Question

As compared to the monsoon and winter a very small quantity of urine is produced in the summer season. Why is it so?

Answer 1

Hint: In humans and in many other animals, urine is a liquid by-product of metabolism. Urine passes from the ureters to the urinary bladder from the kidneys. Urination results in the excretion of urine from the body through the urethra.

Complete Answer:
- Water is an aspect of our metabolism that is important. This is helpful in preserving blood fluidity, flowing nutrients through the body, transporting essential chemicals such as hormones, enzymes, and eliminating waste from the body as well.
- In the form of urine, sweat, faeces, and direct loss (under extremely hot and dry conditions), excess water containing waste is lost from the body via urination, the full amount of surplus water is lost. We dramatically lose water in the form of sweat during the summer when the surrounding temperature is high, direct evaporation.

- Kidneys thus retain water to preserve the blood's fluidity and less urine is produced.But the surrounding temperature would be very low during winter. There's going to be no sweating, no lack of evaporation.
- In addition, the blood capillaries in the skin are constricted and the blood pressure is elevated to maintain the body temperature stable. As a result, our bodies are warmed up. In order to maintain normal blood pressure, the excess water is mostly excreted in the form of urine along with the waste. This is the explanation for pouring out more urine and urinating regularly under very cool conditions and in winter.

- In this respect, adreno-cortico steroid hormones play an important role in transmitting signals to the kidneys. By generating the sensation of thirst, the kidneys will sense and assess the need for water intake.
- For the smooth execution of different metabolic processes that take place in our body, the kidneys maintain the balance of water content in the body.
- Standard urine, composed of uric acid, water, casts, salts and other undesirable products, is either colourless or light yellow, causing no pain when urinating. A highly dehydrated person can not urinate at all. In many diseases, the colour of urine is a warning sign.

Note: In adult humans, average urine output is about 1.4 L of urine per person per day with a normal range of 0.6 to 2.6 L per person per day, produced in approximately 6 to 8 urinations per day, depending on the state of hydration, the level of exercise, environmental conditions, weight, and the health of the individual. Polyuria is a disease in which urine is inappropriately formed (> 2.5 L / day), oliguria produces < 400 mL and anuria produces < 100 mL per day.
