Question

function.. mouth, food pipe, stomach,large intesting, small intesting​

Answer 1

Function of :

Mouth =

The two main functions of the mouth are eating and speaking. The face's trigeminal nerve provides sensation (feeling) and helps us to bite, chew and swallow. Some disorders of the mouth include infections, ulcers, cancer, cleft palate, dry mouth syndrome, dental caries and speech problems such as lisping

Food Pipe =

The food pipe (oesophagus) is part of your digestive system. It is the tube that carries food from your mouth to your stomach. It lies behind the windpipe (trachea) and in front of the spine.

Stomach =

The core function of the human stomach is as an aid to diges- tion. The four key components of gastric digestive function are its function as a reservoir, acid secretion, enzyme secre- tion and its role in gastrointestinal motility.

Large Intestine =

The purpose of the large intestine is to absorb water and salts from the material that has not been digested as food, and get rid of any waste products left over. By the time food mixed with digestive juices reaches your large intestine, most digestion and absorption has already taken place.

Small Intestine =

The small intestine is chiefly involved in the digestion and absorption of nutrients. It receives pancreatic secretions and bile through the hepatopancreatic duct which aid with its functions. In this article, we will discuss the histology, structure and secretions of the small intestine.
