Question
Describe the role of the skin in excretion.
Answer in Brief
Solution
- Skin has many glands, which help excrete waste products through pores. It has two types of glands: sweat and sebaceous glands.
- Sweat glands are highly vascular and tubular glands that separate waste products from the blood and excrete them in the form of sweat. Sweat excretes excess salt and water from the body.
- Sebaceous glands are branched glands that secrete an oily secretion called sebum.
