What is the lining found on the surface of the stomach and small intestine?
Mucosa
What is inflammation of the stomach small intestine and colon known as?
Gastritis is the inflammation of the lining of the stomach.
The enzyme that catalyzes the digestion of peptides in the small intestine is?
The enzyme that catalyzes the digestion of peptides in the small intestine is pepsin. Pepsin is released by the mucosal lining of the stomach.
What protects the lining of the small intestine from the acid that enters this area from the stomach?
The lining of the small intestine is protected from stomach acid by a mucus layer that coats and lubricates the surface. Additionally, the small intestine secretes bicarbonate to help neutralize any acid that enters from the stomach. The rapid turnover of epithelial cells in the intestine also helps to repair and replace damaged cells.
What is an open sore in the lining of the stomach or small intestine?
Open sores that occur inside the stomach lining are called ulcers. Having these ulcers frequently is referred to as open sore stomach.
How is surface area maximized in the stomach and small intestines?
The stomach lining is quite smooth. The small intestine is lined with villi which increases surface area. Think of villi as little round popsicle sticks protruding from the lining.
Does the small intestine have mechanical or chemical digestion?
Yes, in part. Chemical digestion occurs in the mouth (saliva), stomach (gastric acid) and small intestine. The nutrients are mostly absorbed in the walls (lining) of the small intestine.
Food is digested by the lining of this organ?
The lining of the small intestine.
How is self-digestion of the stomach and small intestine prevented?
Self-digestion of the stomach and small intestine is prevented by the mucus lining that protects these organs from the acidic and enzymatic activity of the digestive juices. Additionally, the cells of the stomach and small intestine have tight junctions that prevent digestive enzymes from leaking out and causing harm. The presence of bicarbonate in the mucus also helps to neutralize any excess acid that may come into contact with the lining.
Can you get sick from consuming small pieces of broken glass?
Of course. the glass can cut the lining of your throat, esophagus, stomach, or intestine. This can be fatal.
What is the shape of the stomach in a frog?
In frogs and all other vertebrates lining of stomach and small intestine is made up of mucosa . But mucosa of small intestine possess villi which are finger like projections which increase surface are for absorption .Villi are absent in stomach .the lining in both frogs are think, but the stomach's is shorter than the intestine's In frogs and all other vertebrates lining of stomach and small intestine is made up of mucosa .

What tissue forms the lining of the stomach and the small intestine?
The basic lining of both is stratified squamous epithelium (SSE).However, the type of SSE in stomach and intestines is specially modified for that particular region. For instance, the SSE in the stomach is contains special cells which secrete gastric juices, while at the same time, the lining of the stomach should be able to withstand the acidity of these juices. The SSE lining the [small] intestines on the other hand, contains projections called villi (singular villus) which aid in digestion and also increase the surface area of the intestines; and the SSE also contains goblet cells which secrete mucus.
