The churned food with the saliva then goes into the food pipe called the esophagu sand through food pipe it reaches the stomach. In stomach it stays for 5-6 hours where the food is mixed and grinded and with the help of certain enzymes and acids the food breaks down and becomes of a paste consistency.
Then the food enters the small intestine where the process of breaking down of food continues with the help of the secreation of pancreas that is pancreatic juice and liver is bile. Here, the nutrients and broken down into its simplest form such as proteins are broken into amino acids, fats into fatty acids and then are absorbed.
