What are the two outermost layers of the skin?

The outermost layer of the skin is the epidermis, which serves as the primary barrier protecting the body from environmental factors such as pathogens, UV radiation, and moisture loss. Below the epidermis lies the dermis, which contains a network of connective tissue, blood vessels, and nerve endings, providing strength, elasticity, and nourishment to the skin.

The connection between these layers is crucial for overall skin health. The epidermis is avascular, meaning it does not contain blood vessels, and relies on the dermis for nutrients and support. Thus, understanding the structure and function of these two layers is essential in fields like dermatology and aesthetic practices.

Other options contain combinations of layers that either do not include the significant outer layer (the epidermis) or incorrectly identify the layers as outermost, leading to an incomplete understanding of skin anatomy.
