Explanation
Digestion is the process by which the body breaks down food into smaller molecules that can be absorbed and used for energy, growth, and repair. It begins in the mouth with chewing and enzyme action in saliva, continues in the stomach with acid and enzymes, and is largely completed in the small intestine where nutrients are absorbed into the bloodstream. Undigested material then passes to the large intestine before being eliminated as waste. Explore more Everyday Science MCQs on mcqstutor to keep practicing.
