Q4: How epidermis acts as the first line of defense?

It produce salt and fatty acid that does not leads to survive pathogens and bacteria.



Difference Between Epidermis and Dermis

Skin is the outermost layer of the body and serves as the first line of defense from invading foreign particles. It secrets acids and salt in liquid form. Epidermis is the outermost layer present on the body and the Dermis is the dense irregular connective tissue present beneath the epidermis. Dermis contains body fluids and vein that leads to blood circulation.
