Question

What role do the following play in our digestive system: a) Oesophagus b) Saliva c) Small intestine​

Answer 1

Answer: The role of the following organs in our digestive organs are as follows.

Explanation:

1. Oesophagus: Anatomically and functionally, the oesophagus is the least complex section of the digestive tube. Its role in digestion is simple: to convey boluses of food from the pharynx to the stomach. The oesophagus begins as an extension of the pharynx in the back of the oral cavity.
2. Saliva: The digestive functions of saliva include moistening food, and helping to create a food bolus, so it can be swallowed easily. Saliva contains the enzyme amylase that breaks some starches down into maltose and dextrin. Thus, digestion of food occurs within the mouth, even before food reaches the stomach.
3. Small intestine: The small intestine or small bowel is an organ in the gastrointestinal tract where most of the absorption of nutrients and minerals from food takes place. It lies between the stomach and large intestine, and receives bile and pancreatic juice through the pancreatic duct to aid in digestion.The small intestine carries out most of the digestive process, absorbing almost all of the nutrients you get from foods into your bloodstream. The walls of the small intestine make digestive juices, or enzymes, that work together with enzymes from the liver and pancreas to do this.
