Resistance to trauma and infection.
Protective barrier against pathogens. (this applies to the lashes keeping sweat/dust from the eyes & hairs in the nose preventing particulates from entering the lungs)
Vitamin D synthesis
Skin carries out 1st step of synthesis, liver/kidneys complete the process.
Sensation
To heat, cold, pressure, vibration, pain etc
Thermoregulation
Vasoconstricts to retain heat
Vasodilates to promote cooling. (In addition to sweating)
Nonverbal Communication
Facial expression
Appearance (can speak of self-image & emotional state)
Other functions
Prevents body from absorbing or losing water.
Prevents Ultraviolet radiation from penetrating to deeper tissue layers
Connectivity for underlying musculature.
Cushion for bones, muscle, organs.
