5. Excretion

Superficial

Prevents water loss and the entry of chemicals and microbes, protects against abrasion and UV light, produces Vitamin D, give rise to hair, nails, and glands

Thickest layer

Produces kertain fibers

Produces melanocytes and contribute melanin which protects against UV light

Responsible for the structural strength and flexibility of the skin
