Asymptomatic Showing no symptoms or signs of infection Porous Made or constructed of a material that has openings Nonporus Has no pores or openings and cannot absorb liquid Mycrobacterium Fortuitum Microscopic germ that normally exists in tap water Skin Histology Study of the structure and composition of the skin tissue Skin Physiology Study of the functions of living organisms 6 Skin Functions Protection, Absorption, Secretion, Excretion, Temperature Regulation, Sensation Protection Acid mantle protective barrier made up of sebum, lipids, sweat, and water. Forms a hydrolipidic film to protect the skin from trying out from exposure to external factors. Sensation Responds to touch, pain, cold, heat and pressure Thermoregulation Average internal temp is 98.6° F through evaporation, perspiration, radiation, and insulation Excretion Sudoriferous glands; sweat glands detoxifies the body by excreting excess water, salt, and unwanted chemicals Secretion Sebum; oily substance that protects and lubricates the skin. Sebaceous glands; oil glands. Skin is 50 to 70% water and slows down the evaporation of water Transepidermal Water Loss (TEWL) Absorption Absorbs water, ingredients, oxygen necessary for skin's health. Epidermis Outermost Layer Stratum Corneum
