Many parts of the human body are made up of dead cells, serving various functions. Here are some examples:
- Outer layer of skin (Stratum corneum): This layer acts as a barrier, protecting the body from external elements.
- Nails: Made of keratin, they provide protection for fingertips and toes.
- Hair: Also composed of keratin, hair serves as insulation and protection for the scalp.
- Teeth: The enamel covering teeth is made of dead cells, providing a strong outer layer.
While the body constantly produces new cells, these dead cells play a vital role in our overall health and function.
