Question

Which of the following metabolic wastes are excreted out through sweat?

Answer 1

The human body functions normally at a temperature of about 37 0 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 (mainly sodium chloride). The sweat passes through the pores in the skin and gets evaporated.
