Question

Remembering that cells in the epidermis get all their nutrients via diffusion from the blood vessels in the dermis, why would it be uselful for the connection between the two layers to have more surface area? (Written response)

Answer 1

It will lead to more efficient diffusion

Step-by-step explanation:

The surface area measures the total space an object covers.

Diffusion involves the movement of molecules from the region of higher concentration to the region of lower concentration. The more the space available for diffusion, the faster the rate of diffusion.

Hence, more surface area between the dermis and the epidermis will ensure a more efficient nutrient diffusion process between the two layers.

Answer 2

I think the reason why it would be useful for the connection between the two layers to have more surface area is so it would be better in vascularization process.
