Epidermis
Protects from abrasion, water loss, infection, etc.
Thermoregulatory functions: ↑ or ↓ loss of heat as capillary beds are opened up
(conductive), and production via of sweat (evaporative).
Sensory Reception (thermoreception, pressure, vibration, pain)
Excretion (sweat excretes water, along with sodium, chloride and some potassium, along
with trace amounts of things like lactic acid and urea)
