Digestion is the process by which the body breaks down the food we eat into usable components. When we put food into our mouths digestion has already started, because digestion means breaking food down into smaller molecules, which are then used to fuel the energy, growth, and functioning of the body at many levels.
Although we might not think of it as such, the stomach is a muscular organ that contracts and expands in order to mix the food with digestive juices. The most important part of digestion takes place in the small intestine, where most chemical digestion and absorption of food occurs. As the liquid food paste travels through the small intestine, nutrients are absorbed and enters the bloodstream, traveling to all the body's cells and systems to maintain health and replenish the immune system. The intestines complete the process of digestion.
