How Do Nutrients Reach the Epidermis of the Skin

Question

How do nutrients reach the epidermis of the skin?
A)Nutrients migrate in vesicles from the hypodermis into the epidermis.
B)Diffusion transports nutrients from blood vessels in the dermis into the epidermis.
C)Blood vessels carry nutrients directly into the epidermis.
D)Solute pumping transports nutrients into the epidermis.

Accepted Answer

Nutrients reach the epidermis of the skin through diffusion from blood vessels in the dermis. The dermis contains a network of blood vessels that supply nutrients and oxygen to the skin cells, including those in the epidermis. These nutrients and oxygen diffuse from the blood vessels into the surrounding tissues, including the epidermis.
