Sekretjon
Sekretjon is a biological process in which cells synthesize and release substances for use inside the organism or for export. It encompasses the secretion of enzymes, hormones, mucus, and other fluids. Secretory cells line glands and epithelia throughout the body, and the substances may be released into ducts, into body cavities, or directly into the bloodstream.
Mechanisms and types: Most secretions are released by exocytosis of secretory vesicles. Secretion can be merocrine,
Examples and functions: Exocrine secretions include saliva, sweat, and digestive enzymes that act locally or within
Clinical relevance: Abnormal sekretjon is associated with various disorders. Impaired insulin secretion is central to diabetes
