The muscularis layer of the gastrointestinal (GI) tract is responsible for forming sphincters. These sphincters help regulate the passage of food and fluids through different parts of the GI tract, such as the lower esophageal sphincter, pyloric sphincter, and anal sphincter.
The epiglottis is a flap of tissue that closes over the windpipe during swallowing, preventing food and liquids from entering the airway and causing choking. This mechanism ensures that swallowed material goes into the esophagus and then the stomach, rather than the lungs.
Circular muscles are called sphincters, there are many different sphincter muscles in the human body.

GI=gastrointestinal tract. In other words everything a bit of food passes from you start chewing it until it leaves your body.

The epiglottis is a small flap of tissue at the base of the tongue that prevents food and liquid from entering the windpipe (trachea) during swallowing. It covers the opening of the trachea to direct food and liquid into the esophagus, helping to prevent choking.
liver
All blood leaving the GI tract first goes to the liver through the hepatic portal vein for processing and detoxification before entering the general circulation.

The four bodily sphincters are the: 1. lower esophageal sphincter, or cardiac sphincter (esophagus to the stomach)2. Pyloric sphincter (stomach to small intestines)3. Ileocecal sphincter or valve (small intestines to large intestines)4. Anal sphincter (rectum to outside)
The stomach has the thickest walls and the strongest muscle in all the GI tract organs. : )
