Here's a breakdown of the terms:
* Simple: Indicates that the duct does not branch.
* Tubular: Refers to the shape of the secretory units, which are elongated and tube-like.
Examples of simple tubular glands:
* Intestinal glands: These glands secrete digestive enzymes and mucus into the small intestine.
* Sweat glands: These glands produce sweat, which helps regulate body temperature.
* Mucous glands: These glands secrete mucus, which lubricates and protects surfaces.
Other types of glands:
* Simple acinar glands: These glands have spherical secretory units and a single, unbranched duct.
* Compound glands: These glands have branched ducts.
