GENERAL HISTOLOGY

Detailed explanation-1: -Serous membranes line body cavities that do not open directly to the outside, and they cover the organs located in those cavities. Serous membranes are covered by a thin layer of serous fluid that is secreted by the epithelium.

Detailed explanation-2: -Serous membranes have two layers. The parietal layers of the membranes line the walls of the body cavity (pariet-refers to a cavity wall). The visceral layer of the membrane covers the organs (the viscera). Between the parietal and visceral layers is a very thin, fluid-filled serous space, or cavity.

Detailed explanation-3: -Epithelial tissues form the covering of all body surfaces, line body cavities and hollow organs, and are the major tissue in glands.

Detailed explanation-4: -mucous membrane, membrane lining body cavities and canals that lead to the outside, chiefly the respiratory, digestive, and urogenital tracts.

Detailed explanation-5: -Epithelial Membranes The mucous membrane is also a composite of connective and epithelial tissues. Sometimes called mucosae, these epithelial membranes line the body cavities and hollow passageways that open to the external environment, and include the digestive, respiratory, excretory, and reproductive tracts.
