Question

Answer the following:
(ii) State the functions of sweat and sebaceous glands.

Answer 1

Part 1: Functions of sweat glands

• Sweat glands produce a watery secretion called sweat that is released on the surface of skin and helps to control the body temperature.
• The sweat consists of water, sodium salts, and nitrogenous waste (such as urea)

Part 2: Functions of sebaceous glands

• Sebaceous glands secrete sebum which contains substances that spread along the hair and onto the skin where it keeps the follicle free from dust and bacteria.
• The oily substance forms a cover on skin that helps prevent water loss.
