No. its chemical
the physical change in the change in food when the enters esophagus is when it has a chemical breakdown in your mouth with a mechanical breakdown the chemical breakdown is when your salivia is making the food moist the mechanical is when you chew the food so it easier for it to enter the esophagus and so the salivia can get it moist then your esophagus uses muscles to push the food down into your stomache
duodenum
The stomach receives food from the esophagus. Once food travels through the esophagus, it enters the stomach where digestion begins.
Digestion involves both physical and chemical changes. The teeth crush food into smaller particles, which is a physical change, whereas the saliva, stomach, gall bladder, and pancreas contain chemicals that break down food chemically in the mouth, stomach, and small intestines.
Yes, barfing is a physical change because it involves a change in state and appearance of food without altering its chemical composition. The food that is consumed undergoes physical changes as it comes back up from the stomach.
The cardiac sphincter or aka GE junction contracts at the distal end of the esophagus. So food enters into the stomach when the cardiac sphincter is relaxed.
bolus
Once food enters your mouth, saliva begins to break it down. When you swallow, the food moves down your esophagus to your stomach. The act of swallowing is also called deglutition.
After the stomach, food enters the small intestine in the digestive system.
food will be absorbed
Its a chemical change. A physical change is a change which does not change the type of matter. The reactions in your stomach break down the matter into other substances.
