Answer 2

The substance that is not normally in sweat is protein.

• Sweat glands present on the skin produce sweat. sweat glands also called sudoriferous glands.
• These are exocrine glands as they secrete their secretion on the surface of epithelia via the ducts.
• An increase in body temperature activates the sweat glands naturally.
• Sweat normally contains urea, salt, lactic acid and water.
• It does not contain proteins as they are large molecules and cannot transmit easily.
• Sweat regulated the body temperature and electrolyte balance. it cools the body due to perspiration from the skin surface.
