Thick layer of mucous your stomach and intestines create hourly.
It is called the Pylorus.
Lower Esophageal Sphincter
The hole that allows food from the stomach into the small intestine is called the pylorus. It is a muscular valve located at the lower end of the stomach. When it relaxes, it allows the partially digested food (chyme) to pass from the stomach into the small intestine.
Stomach, Small intestine, and colon
An operation where a portion of the lower stomach (pylorus) is removed. The remaining portion of the stomach is then connected to the duodenum (first part of the small intestine).
lower esophageal sphincter or gastroesophageal sphincter
It regulates the exit of partially digested food from the stomach and is in the lower region of the stomach
When you say "lower digestive system" I'm assuming you mean your intestines. If that is what you're referring to, it starts at the bottom of your stomach. The bottom of your stomach is connected to your small intestine, which then goes to your large intestine, then to your rectum, and then your anus.
The Pyloric Sphincter controls the movement of food between the stomach and the small intestine.
the stomach lining is made up of a histological layer (tissue layer) called "mucosa". as we gather from the name the layer constitutes mainly of mucous. the stomach is a site for churning and digestion of food with the help of enzymes like pepsin and hydrochloric acid (HCl). this acid can also harm the stomach muscles causing lesions which we popularly know as "peptic ulcers". the mucosa layer prevents the stomach muscles from coming in contact with the acid thus preventing the occurence of ulcers.
The ring of muscle at the entrance to the stomach is the lower esophageal sphincter. This muscle is normally contracted to close the esophagus. At the lower end of the stomach food passes through the pyloric sphincter and into the duodenum of the small intestine.
