The skin is composed of epithelial tissue. This tissue forms a protective barrier that covers the body's surface and lines internal organs. The skin's outer layer, the epidermis, is made up of epithelial cells that constantly regenerate, shedding dead cells as new ones form.
The skin also contains other types of tissue, including:
- Connective tissue: This tissue provides support and structure to the skin, helping it maintain its shape and elasticity.
- Muscle tissue: This tissue allows the skin to move, such as when we shiver or contract our muscles.
- Nervous tissue: This tissue helps the skin to sense touch, temperature, and pain.
The skin is a complex and vital organ, playing a crucial role in protecting the body from environmental hazards, regulating body temperature, and maintaining hydration.
