Question 35-Describe the structure and function of cutaneous, mucous, and serous membranes

1) Cutaneous Membranes-It is an organ system consisting of a keratinized stratified squamous epithelium, which is then attached to a thick layer of irregular connective tissue. Otherwise know as your skin. This membrane is dry and exposed to the air.
2)Mucous Membrane-This membrane lines the body cavities open to the outside, like the digestive, respiratory, and urogenital tracts. They are usually wet membranes that bathe in the secretions. This lubricates the areas, so they can move comfortably. Only the digestive and respiratory tracts secrete lots of lubricating mucus, but the urinary tract does not.
3) Serous Membranes-these are the most moist membranes found in the closed ventral cavites. It consists of simple squamous epithelium which is laying on a thin layer of loose areolar tissue. The mesothelial cells enrich the fluid from the capillaries and the hyaluronic acid. This creates serous fluid that lubricates the surfaces, so they slide across each other with ease.
