The mucous membranes (or mucosae; singular mucosa) are linings of mostly endodermal origin, covered in epithelium, which are involved in absorption and secretion. Latin ( lingua Latīna, laˈtiːna is an Italic language, historically spoken in Latium and Ancient Rome. Gray's Anatomy the Respiratory apparatus ( Apparatus Respiratorius Respiratory system Respiratory apparatus Elsevier, the world's largest Publisher of Medical and Scientific literature, forms part of the Reed Elsevier group A germ layer is a collection of cells formed during animal Embryogenesis. In biology and medicine epithelium is a tissue composed of cells that line the cavities and surfaces of structures throughout the body Digestion is the breaking down of chemicals in the body into a form that can be absorbed Secretion is the process of segregating elaborating and releasing chemicals from a cell, or a secreted Chemical substance or amount of substance They line various body cavities that are exposed to the external environment and internal organs. In Biology, an organ ( Latin: organum, "instrument tool" from Greek όργανον - organon "organ instrument It is at several places continuous with skin: at the nostrils, the lips, the ears, the genital area, and the anus. The skin is the outer covering of living tissue of an animal (or plant Lips are a visible body part at the mouth of humans and many animals The ear is the sense organ that detects Sounds The Vertebrate ear shows a common biology from Fish to Humans with variations A sex organ, or primary sexual characteristic, as narrowly defined is any of the anatomical parts of the body which are involved in sexual reproduction and constitute The anus is an opening at the opposite end of an Animal 's Digestive tract from the Mouth. The sticky, thick fluid secreted by the mucous membranes and gland is termed mucus. A gland is an organ in an animal's body that synthesizes a substance for release such as Hormones or Breast milk, often into the Bloodstream In vertebrates mucus is a slippery secretion produced by and covering Mucous membranes It is a viscous Colloid containing Antiseptic enzymes (such as The term mucous membrane refers to where they are found in the body and not every mucous membrane secretes mucus. With regard to living things, a body is the integral physical material of an individual

Body cavities featuring mucous membrane include most of the respiratory system. In living organisms a respiratory system functions to allow Gas exchange. The glans penis (head of the penis) and glans clitoridis and the inside of the prepuce (foreskin) and clitoral hood are not mucous membranes; however, the urethra is a mucous membrane. The glans penis (or simply glans) is the sensitive tip of the Penis. The penis (plural penises, penes The clitoral glans (glans clitoridis is an external portion of the Clitoris. In Female Human Anatomy, the clitoral hood, (also called preputium clitoridis and clitoral prepuce) is a fold of Skin The secreted mucus traps the pathogens in the body, preventing any further activities of diseases.
