we eat meat and also digest it,but we know that our stomach is also a meat like thing.then why not it digest by us.
Answers
Answer:
In basic terms—Our stomachs take care of mechanical digestion (breaking down the large insoluble bits), but actual absorption of nutrients doesn't take place in the stomach—for the most part. This happens in the small intestine. When you eat proteins, they have to be broken down before they can be absorbed. Since liquid does’t have to go through this process, it takes a faster track to the small intestines.
Explanation:
Your stomach lining, or mucosa, has glands that produce stomach acid and other important compounds. One example is the enzyme pepsin. While your stomach acid breaks down food and protects you from infection, pepsin breaks down protein. The acid in your stomach is strong enough to damage your stomach. So, your stomach lining secretes mucus to protect itself.
Gastric mucosa
The inner surface of the stomach is lined by a mucous membrane known as the gastric mucosa. The mucosa is always covered by a layer of thick mucus that is secreted by tall columnar epithelial cells. Gastric mucus is a glycoprotein that serves two purposes: the lubrication of food masses in order to facilitate movement within the stomach and the formation of a protective layer over the lining epithelium of the stomach cavity. This protective layer is a defense mechanism the stomach has against being digested by its own protein-lyzing enzymes, and it is facilitated
by the secretion of bicarbonate into the surface layer from the underlying mucosa.
