Secretory

"Secretory" in a Sentence (2 examples)
The most likely path a protein will take after being created is as follows: after a protein is made in the RER, it is sent via a transition vesicle to the Golgi apparatus, where it is processed, and then sent to its final destination in a secretory vesicle.
As has been very justly remarked, we cannot properly regard these cells as secretories.
