name the 4 types of cells and their functions
These four main cells and their function:- 1) Epithelial Cells:-They cover over the interior of hollow organs, like blood vessels or digestive organs, or else form the surface of things, like the skin. Without epithelial cells, you would have no skin to protect your body from injury and would have no stomach to digest your food. 2). Nerve Cells. These cells are specialized for communication. They send signals from the brain to muscles and glands that control their functions. 3).Muscle Cells. These cells are specialized for contraction. Without muscle cells, you would not be able to move. 4).Connective Tissue Cells. These cells provide structural strength to the body and also defend against foreign invaders like bacteria. Regards
