The answer is an exocrine gland.
Exocrine glands are a group of cells that secrete fluid through the duct and not directly into the bloodstream like endocrine glands. These glands can be found in the skin (sweat glands) and mouth (salivatory glands), as well as in digestive or respiratory tracts. Sometimes, they can even release substances out of the body, such as lacrimal or sweat glands. They are responsible for different life processes, like temperature regulation (sweat glands)
