The smallest dead cell is a keratinocyte, specifically those found in the stratum corneum layer of the skin. This layer is the outermost layer of the epidermis and is composed of dead keratinocytes.
The stratum corneum acts as a barrier to protect the body from environmental factors, including bacteria, UV radiation, and dehydration. The dead keratinocytes in this layer are filled with keratin, a tough protein that gives the skin its structure and strength.
Other dead cells can include:
- Red blood cells: These cells lose their nuclei and organelles during maturation, becoming specialized for oxygen transport.
- White blood cells: Some white blood cells, like neutrophils, die after engulfing pathogens, contributing to the body's immune response.
