Word Origin & History

O.E. slim "slime," from P.Gmc. *slimaz (cf. O.N. slim, O.Fris. slym, Du. slijm, Ger. Schleim "slime"), probably related to O.E. lim "sticky substance," from PIE base *(s)lei- "slime, slimy, sticky, slippery" (cf. Rus. slimak "snail;" O.C.S. slina "spittle;" O.Ir. sligim "to smear;" Welsh llyfn "smooth;"
Gk. leimax "snail," limne "marsh, pool, lake;" L. limus "slime, mud, mire," linere "to daub, besmear, rub out, erase;" see lime (1)). The verb meaning "to cover with slime" is recorded from 1628. The figurative sense of slimy as "morally repulsive" is first attested 1575.

viscous fluid that moistens, lubricates, and protects many of the passages of the digestive and respiratory tracts in the body. Mucus is composed of water, epithelial (surface) cells, dead leukocytes, mucin, and inorganic salts. Mucus is produced by mucous cells, which are frequently clustered into small glands located on the mucous membrane that lines virtually the entire digestive tract. Large numbers of mucous cells occur in the mouth, where mucus is used both to moisten food and to keep the oral membranes moist while they are in direct contact with the air. Mucus in the nose helps to trap dust, bacteria, and other small inhaled particles. The stomach also has large numbers of mucous cells. Gastric mucus forms a layer about one millimetre thick that lines the stomach, protecting the organ from highly acidic gastric juice and preventing the juice from digesting the stomach itself.
