The papillary layer of the dermis is composed of loosely packed connective tissue with numerous peg-like projections that provide a great deal of surface area connecting the dermis to the epidermis.Which of the statements below do not represent benefits provided by the papillary layer's anatomy?
A) The spaces in the connective tissue allow many small blood vessels to deliver nutrients and pickup waste diffusing from the superficial epidermal layers.
B) The looseness allows for easy separation of the dead cell layer of epidermis to be shed.
C) The high surface area allows for a stronger connection of dermis to epidermis.
D) The looseness allows for phagocytes to roam through the tissue and search for infection.

The papillary layer's looseness and high surface area primarily facilitate nutrient delivery, waste removal, a strong connection between the dermis and epidermis, and immune surveillance by phagocytes. It does not directly facilitate the shedding of the dead cell layer of the epidermis, which is a process more associated with the properties and activities within the epidermis itself rather than the characteristics of the papillary layer of the dermis.
