secretion

1. the cellular process of elaborating a specific product. This activity may range from separating a specific substance of the blood to the elaboration of a new chemical substance.

2. any substance produced by secretion. One example is the fatty substance produced by the sebaceous glands to lubricate the skin. Saliva, produced by the salivary glands, and gastric juice, secreted by specialized glands of the stomach, are both used in digestion. The secretions of the endocrine glands include various hormones and are important in the overall regulation of body processes. Secretion of milk is an essential physiological activity in all mammals. Secretion of tears in animals has a simple protectory function and has no overriding emotional involvement.

3. categories of secretion include apocrine, holocrine, merocrine, sebaceous, serous.

This flow out of a cell is driven by an osmotic pressure gradient across the membrane, which is created by active transport of one or more ion species from one side to the other. See active transport; ultrafiltration.
