Exocrine secretions are released into which locations?

Explanation:
Exocrine secretions are released onto epithelial surfaces or through ducts. This means glands like salivary, sweat, and pancreatic ducts transport their products to body surfaces or into hollow organs, rather than releasing them into the bloodstream. This is what sets exocrine glands apart from endocrine glands, which release hormones directly into the bloodstream to travel to distant targets. Releasing into the bloodstream would be endocrine, not exocrine. The nucleus is not a site of secretion, and exocrine products are not confined to the interstitial space as their final destination; they are specifically aimed at surfaces or ducts that lead to surfaces.
