A skin raft is best described as?

A skin raft refers to the layer of dead skin cells that continuously shed from the human body, which occurs at a rate of approximately 50,000 cells per minute. This process is a natural part of the skin's lifecycle, where older cells at the outermost layer (the stratum corneum) are replaced by new cells generated from deeper layers. This shedding helps maintain skin health by removing old cells, enabling new cell growth, and preventing the buildup of dead skin on the surface.

Understanding that skin rafts consist of dead skin cells highlights the importance of skin renewal and the constant cycle of cell turnover that is vital for maintaining the skin's barrier function and overall appearance. Each day, a person can lose a significant amount of skin, which contributes to dust and allergens in the environment. This biological process is an essential aspect of skin physiology and homeostasis.
