Question

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 layers anatomy?
the spaces in the connective tissue allow many small blood vessels to deliver nutrients and pick up waste diffusing from the superficial epidermal layers.
the high surface area allows for a stronger connection of dermis to epidermis.
the looseness allows for phagocytes to roam through the tissue and search for infection.
the looseness allows for easy separation of the dead cell layer of epidermis to be shed.

Explanation:

Brief Explanations
  • The papillary layer's loose connective tissue and peg - like projections have functions related to nutrient delivery (small blood vessels in spaces), stronger dermis - epidermis connection (high surface area), and phagocyte movement (looseness for phagocytes).
  • Shedding of the dead epidermal cell layer (stratum corneum) is mainly related to the epidermis itself and desmosome degradation in the stratum corneum, not a direct function of the papillary layer's anatomy.

Answer:

The looseness allows for easy separation of the dead cell layer of epidermis to be shed.
