Food needs to be digested to break it down into smaller molecules that can be absorbed by cells for energy. The process of digestion involves various organs in the digestive system. Digested food is absorbed in the small intestine, and waste is eliminated through the large intestine.
Food needs to be digested because most food in its original form is not in a state that cells can directly utilize. The process of digestion breaks down food into smaller molecules that can be absorbed into the bloodstream and then utilized by cells for energy or building new molecules.
When food is digested in our bodies, it goes through the digestive system starting from the mouth, continuing through the esophagus, stomach, small intestine, and large intestine. Enzymes and acids help break down food into smaller particles as it moves through these organs.
The digested food is primarily absorbed in the small intestine. Nutrients from the broken-down food are absorbed into the blood vessels lining the small intestine, and any remaining waste is processed in the large intestine before being excreted through the anus.
