TED-ED: The science of skin - Emma Bryce

The video explores the skin, the body's largest organ, covering its structure, functions, and roles. Skin is part of the integumentary system, consisting of three layers: epidermis, dermis, and hypodermis. It serves as a protective barrier, regulates temperature, and provides sensory input. The epidermis is a waterproof layer, while the dermis contains collagen and immune cells. Skin also hosts microorganisms that aid in immune defense. Temperature regulation involves blood vessels and sweat glands, with hair follicles playing a role in heat conservation. Overall, skin is vital for protection, sensation, and temperature control.
