A simple branched acinar gland is a type of exocrine gland that has a single, unbranched duct leading from the secretory units. These secretory units are rounded, sac-like structures called acini.

Here's an example:

Sebaceous glands are a classic example of simple branched acinar glands. These glands are located in the skin and produce sebum, an oily substance that lubricates and waterproofs the skin and hair.

Here's how they work:

* Secretory units (acini): The sebaceous glands have clusters of acini, each containing secretory cells that produce sebum.

* Duct: Each cluster of acini is connected to a single, unbranched duct that empties into a hair follicle.

Other examples of simple branched acinar glands include:

* Some sweat glands

* Certain glands in the digestive system

It's important to note that while these glands are categorized as "simple," they can have a complex branching pattern within the secretory units.
