Act as a waterproof cover and it protects the body from dehydration, infection and harmful chemicals. Skin tone also created by the epithelium. Melanocytes containing in the epithelium gives skin colour to each human. It nourishes by the diffusion from the dermis due to the absence of blood vessels.
- Dermis – Situated just beneath and toughly connected to the epidermis. It contains tough connective tissue, hair follicles, and sweat glands. There are nerve endings in this layer feels a sense of touch and heat. Dermis nourishes from the blood vessels through the layer. Sweat gland produce sweats and sebaceous gland produce sebum.
