The four types of tissue membrane consist of an epithelium supported by connective tissue. What do the qualities of each of these two tissues contribute to the function of the membrane? Use one type of tissue membrane as an example
The connective tissue provides structural support and strength, and its blood supply sustains the membrane. The epithelial tissue gives a smooth surface that protects against friction by being slippery (or keratinized, for cutaneous membrane), it is secretory (mucus, serous fluid, synovial fluid, sweat and skin oil), and it may control the passage of materials (for example, cutaneous membrane reducing water loss from the body).
