Digestion is the breakdown of Cloze (1): JXUwMDM0JXUwMDBkJXUwMDEzJXUwMDE1JXUwMDAy insoluble food molecules into small water-soluble Cloze (2): JXUwMDNlJXUwMDA5JXUwMDAwJXUwMDBi molecules so that they can be absorbed into the watery blood plasma. In certain organisms, these Cloze (3): JXUwMDJiJXUwMDFlJXUwMDBjJXUwMDBkJXUwMDAwJXUwMDA5JXUwMDE3 substances are absorbed through the small intestine into the blood stream. Cloze (4): JXUwMDFjJXUwMDJkJXUwMDBlJXUwMDAyJXUwMDE2JXUwMDA3JXUwMDFkJXUwMDA2JXUwMDAx is a form of catabolism that is often divided into two processes based on how food is broken down: mechanical and Cloze (5): JXUwMDNiJXUwMDBiJXUwMDBkJXUwMDA4JXUwMDA0JXUwMDBhJXUwMDAyJXUwMDBk digestion. The term mechanical digestion refers to the physical breakdown of large pieces of food into Cloze (6): JXUwMDJiJXUwMDFlJXUwMDBjJXUwMDBkJXUwMDAwJXUwMDA5JXUwMDE3 pieces which can subsequently be accessed by digestive enzymes. In chemical digestion, enzymes break down food into the small Cloze (7): JXUwMDM1JXUwMDAyJXUwMDAzJXUwMDA5JXUwMDA2JXUwMDE2JXUwMDE5JXUwMDA5JXUwMDE2 the body can use.
