"Skin of Mammals | Structure and Functions"

The skin of mammals is thick and complex, serving as a protective barrier and helping regulate body temperature. It consists of three main layers: Epidermis – The outermost layer, which produces keratin to form hair, nails, and protective coverings. Dermis – The middle layer, containing blood vessels, nerves, sweat glands, and sebaceous (oil) glands. Hypodermis – The innermost layer, made of fat and connective tissue, which provides insulation and cushioning. Mammalian skin has hair or fur, which helps in temperature regulation, camouflage, and protection. Sweat glands help cool the body, while sebaceous glands keep the skin and hair moisturized. Some mammals, like whales and dolphins, have a thick layer of fat (blubber) instead of fur to keep them warm in cold waters. #skin of Mammals
