HEYA..!!!!
The food gets digested completed in small intestine and also assimilated through the villi .Partially digested food, or chyme, from the stomach is mixed with bile from the liver and pancreatic juice from the pancreas to complete its digestion in the duodenum. The jejunum is the middle section of the small intestine that serves as the primary site of nutrient absorption.
hope this helps you :)

Firstly the food gets mixed with salivary amylase which is an enzyme present at saliva. Salivary amylase breaks down starch and then food goes towards stomach through food pipe. Food moves there by peristaltic movement by sphincter cells. Food now mix with HCL acid present in stomach for killing of bacteria present at mouth. Mucus helps the stomach for protecting the inner linning of stomach. HCL acid also active pepsin enzyme which synthesis proteins. It is also present at mouth. Bile juice present at liver help to synthesis the fat molecules
