Hloo dear..!!!
1. Adipose tissue present in the subcutaneous tissue prevents heat loss form the body during excessive cold.
2. Sebaceous glands present on skin secrete an oily or wax-like secretion called sebum which keeps the skin oily and thus prevents the entry of germs inside the body.
3. Our skin contains a pigment called melanin which prevents us from exposure to ultra-violet rays.
