PATHOLOGY

Detailed explanation-1: -Skin, hair, and nails are made of similar types of cells. They form the outer layer of the body, called the integumentary (in-teh-gyoo-MEN-tah-ree) system. It protects everything inside the body.

Detailed explanation-2: -The integumentary system is a complex organ that helps protect the body and regulates various essential processes. It comprises the skin, hair, nails, and glands that produce sweat and oil. These tissues work together to protect the body from infection and injury and regulate bodily processes.

Detailed explanation-3: -What Do Nails Do? Nails protect the sensitive tips of fingers and toes. We don’t need our nails to survive, but they do support the tips of our fingers and toes, protect them from injury, and help us pick up small objects. Without them, we’d have a hard time scratching an itch or untying a knot.
