Is the large intestine a physical or chemical change?

What is a chemical change in the digestive system?
When it comes to digestion, chewing is only half the battle. As food travels from your mouth into your digestive system, it’s broken down by digestive enzymes that turn it into smaller nutrients that your body can easily absorb. This breakdown is known as chemical digestion.
Why is digestion a chemical change?
Chemical digestion is considered a chemical change because enzymes in the stomach and intestines break down large macromolecules into simpler molecules so that the body can more easily absorb the food.
Does most chemical digestion occur in the large intestine?
The chyme is slowly transported into the small intestine, where most chemical digestion takes place. Bile, which is made in the liver, is released from the gallbladder to help digest fats. In addition, enzymes from the pancreas and intestinal walls combine with the chyme to start the final part of digestion.
What does the large intestine absorb?
