What is the role of the papillary layer in the skin?

  1. Producing keratin for hair and nails

  2. Regulating body temperature

  3. Connecting the epidermis to the dermis

  4. Serving as a barrier to pathogens

The correct answer is: Connecting the epidermis to the dermis

The papillary layer of the skin serves as a connection between the epidermis (outer layer) and the dermis (inner layer). This layer is rich in connective tissue, blood vessels, and nerve endings that help nourish and support the epidermis. The other options mentioned, such as producing keratin, regulating body temperature, and serving as a barrier to pathogens, are functions of other layers of the skin and are not related to the role of the papillary layer.
