Digestion is the breakdown of large molecules (food) into small soluble molecules. This is done by digestive juices and enzymes. Once food is digested it can pass through your gut wall into your blood. Your blood then carries the digested food all around your body where it is used for growth, movement and repairing cells. The digestive system is a group of organs working together to convert food into energy and basic nutrients to feed the entire body. This lecture briefly present on how does digestion work and what happens to your food when you swallow.
