Diagram of the Stomach Lining
Most of the digestive system in simple terms are sacs or bags connected by pipes and tubes.
The Stomach environment is very acidic. This acid environment kills germs and reduces foreign substances
making it an incredibly important part of our immune system.
The muscles of the stomach are strong and churn the food.
The mucosal layer excretes mucous which protects the stomach lining from burning due to the very acidic
The sub mucosa is fibrous connective tissue that separates the mucosa from the muscular layer.
The stomach lining is one of the most interesting anatomical parts of our bodies. The purposes
of the stomach are to break down food and sterilize potentially harmful microbes and substances.
Many hormones are produced, the main one being Gastrin which breaks down proteins..
Other hormones are Chiolecystokinin, Secretin, Gastric Inhibitory Peptide, and Enteroglucagen.
Gastric Acid is produced in the stomach lining.
Overview of the Stomach Lining
The churning sac mixes and tries to break down food like a washing machine.
In the highly acidic environment, almost nothing can survive. This protects us from germs and disease
Due to the dangerous qualities of the acid environment, the stomach needs to produce and coat itself with
mucous for protection. if not
The acid would eat through the lining and kill us, or at least give us sores and ulcers.
Our bodies add enzymes to the acidic mix which are stimulated by hormones.
Medicines and the Stomach Lining
Most medicines that treat ulcers and gastritis are made to act on the stomach lining. You can read about
