 The winds that move from cold upland areas into lower elevations under the influence of gravity are described as  katabatic winds. They are also called downslope winds, or gravity winds.
These winds carry high-density air from a higher elevation (mountains, plateaus, and hills )down a slope under the force of gravity. The katabatic winds occur at night, when the highlands radiate heat and are cooled.

the glands which are associated with each description is given below:

pancreas - is an endocrine and exocrine gland that secretes juices with enzymes for digestion. salivary glands- with protection and digestion in the mouth. liver- secretes bile for digestion.   lachrymal glands - secrete tears to moisten eyes and protect them from particles and infection.   sweat gland -regulates water, salt, and temperature. oil glands - to form a protective barrier on the skin.   goblet cells - secrete mucus for protection.
