How does skin protect the body?

The skin protects us from microbes and the elements, helps regulate body temperature, and permits the sensations of touch, heat, and cold. Skin has three layers: The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone.

How skin works as a sense organ?

Sensory Function The skin acts as a sense organ because the epidermis, dermis, and the hypodermis contain specialized sensory nerve structures that detect touch, surface temperature, and pain.

How does skin prevent dehydration?

Control water loss: the skin prevents water from escaping by evaporation. Water resistance: it prevents nutrients from being washed from the skin. Thermoregulation: by producing sweat and dilating blood vessels, the skin helps keep the body cool. “Goosebumps” and blood vessel constriction, help us retain heat.
