Question

Why do we sweat?

Short Note

Solution

Sweat palys an important role in maintaining body temperature. The human body functions normally at a temperature of about 37°C. When it gets hot sweat glands start secreting sweat, which contains water with small amounts of other chemicals like ammonia, urea, lactic acid and salts. This helps in cooling the body.
