Gland that secretes through ducts to the surface of an organ or tissue or into a vessel is called

Exocrine gland.

Explanation:

The exocrine gland secretes through ducts opening in a gland to the surface of an organ or tissue or into a vessel of the body. Sweat glands (secreting sweat) and salivary glands (secreting saliva) are the best-known examples of exocrine glands. These both gland acting on local tissue which is present near to the duct opening.

In structure, exocrine glands are classified by their different shape of secretory parts, and the arrangement of their ducts. These are unicellular, multicellular and goblet cells in nature.
