Expert Answer:

There are two functions of a gastric sphincter. This sphincter connects the digestion to the body of the stomach and also releases digested food to the duodenum.
Internal anal sphincter is made of smooth muscle and is a thickening of the circular layer of the muscularis. Contracts involuntarily.

External anal sphincter is made of skeletal muscle and is a distinct muscle. It contracts voluntarily to inhibit defecation.
