Final answer:
The flaky layer of the epidermis is the stratum corneum, which forms a waterproof barrier and sheds dead cells.
Step-by-step explanation:
The flaky layer of the epidermis is the stratum corneum, which is the most superficial layer of the epidermis. This layer is composed of dead, flat, and tightly packed keratinocytes. It forms a waterproof barrier to protect the underlying layers of the epidermis and is constantly shedding dead cells that are replaced by new cells from lower layers.
