Digestion is a process that helps to convert complex substances into a simple form. It converts the ingested food into an absorbable form. The digestion process involves chemical and physical digestion processes. In physical or mechanical digestion food is broken down into smaller pieces it begins from teeth and it further continues in the stomach and small intestine through the churning process. In chemical digestion macromolecules in food are converted into smaller or simple molecules that can be easily absorbed into body fluids and transported to cells throughout the body. Chemical digestion involves digestive enzymes like salivary amylase, pepsin, lipase, etc. So take this quiz and know more about the digestive system.
