what are secretory cells

Secretory cells are specialized cells that perform the function of secretion. They are found in various organs and tissues of the body, including exocrine glands, endocrine glands, and epithelial cells. Secretory cells can be classified into two types: neurosecretory cells and exocrine secretory cells. Neurosecretory cells are neurons that secrete substances directly into the bloodstream to act as hormones. Exocrine secretory cells are multicellular glands that are grouped together and organized to act as secretory organs. The secreted material can be protein, hormones, enzymes, or other substances. The rough endoplasmic reticulum is usually conspicuous in secretory cells that secrete protein. Secretory cells are important for various physiological processes, including digestion, lactation, and hormone regulation.
