General Functions
Integumentary System
Functions as an organ, actually the largest organ of the body and also possesses all four tissue types, Nervous, Muscular, Epithelial, and connective.
Excretion
helps remove waste from the body through an excretory system where salts, urea, and water are lost through the process of sweating
Vitamin D Production
cells in the epidermis use ultraviolet radiation to synthesize vitamin D, vitamin D is needed for the absorption of calcium through our digestive tract.
Temperature Regulation
capillary networks and sweat glands in the skin regulate heat loss from the body, helping control temperature of the body.
Sensory Reception
The skin has sensory receptors that are associated with nerve endings, they have the ability to sense pressure, touch, temperature, and also alert us if we are in pain. It acts as an awareness system of the surface of the body.
Protection
It protects internal tissues and organs from damage or penetration, also against organisms that cause infection. while also keeping the body from dehydrating
Hypodermis
consists primarily of adipose tissue, lies under the skin, insulates the body against heat loss, and protects the body from damage. this layer is known to store larger amounts of body fat
