Question

Give any two functions performed by epithelial tissue.

✓

Answer

Functions of the epithelial tissue are:

The cells of the body surface (i.e., epidermis) from the outer layer of skin. These cells protect the underlying cells from drying, injury and chemical effects. They also protect the body from viral or bacteria infection.
Epithelial tissues help in absorption of water and nutrients.
Epithelial tissues help in elimination of waste products.
Some epithelial tissues perform secretary function. They secrete a variety of substances such as sweat, saliva, (mucus), enzymes, etc.
