Yes, skin is considered an organ. It's the largest organ in the human body, covering the entire external surface. The skin is made up of three layers: the epidermis, dermis, and hypodermis. Each layer has its own unique structure and function, working together to protect the body from the environment, regulate temperature, and sense touch.
- Epidermis: The outermost layer, responsible for protection and acting as a barrier against infection and dehydration.
- Dermis: The middle layer, containing blood vessels, nerves, hair follicles, and sweat glands, supporting the epidermis and providing nourishment.
- Hypodermis: The innermost layer, made of fat and connective tissue, anchoring the skin to underlying muscles and providing insulation.
The skin and its appendages, like hair, nails, sweat and oil glands, collectively form the integumentary system.
