compare the process of digestion in stomach and small intestine
Answers
Answer:
here is the answer
Explanation:
The food begins its journey from the mouth where the tongue rolls it and teeth break it into pieces, while saliva softens it to begin the process of digestion. It further goes down the digestive system.
The walls of the digestive system are muscular and move constantly to propel food through it, simultaneously mixing the contents within each organ. This movement is known as peristalsis.

Answer:
THE STOMACH
The stomach coats the food with a mixture of acid and digestive enzymes to help break the food down further. A layer of mucous protects the stomach lining from being damaged by the acid.
The bottom of the stomach is able to contract, which helps to speed up the process. When the food is broken down sufficiently the stomach releases its contents into the duodenum.
THE SMALL INTESTINE
The small intestine is categorised in three parts; the duodenum being the first, the jejunum second and the ileum the final part.
When food enters the duodenum, the pancreas releases enzymes to help break down fat , protein and carbohydrate The gall bladder releases bile, which has been produced by the liver, to help further break fats down into a form that can be absorbed by the intestines.
