What Are the Functions of the Integumentary System?
Without the integumentary system, we wouldn't be able to survive. The integumentary system works to protect, store, and regulate body temperature. It protects us from germs, dehydration, and injury. It manufactures vitamin D so that our digestive system can absorb calcium, and it also stores glucose, fat, water, and even salt. It even protects us from harmful sun rays.
Organs and Tissues
There Isn't Just One Kind of Tissue
The dermis, or the layer under the epidermis, contains sensory cells for heat, cold, pain, and pressure, and also contains subaceous glands and sweat glands. It is made of matted masses of connective tissue, elastic fibers, nerve endings, muscles, and hair follicles.
The hypodermis stores half the body's fat and absorbs shock. It is a loose, connective tissue.
