The movement of small organic molecules, electrolytes, vitamins, and water across the digestive epithelium and into the interstitial fluid of the digestive tract is referred to as absorption. This process is essential for obtaining nutrients from the food we eat and delivering them to our body's cells. Secretion refers to the release of substances, ingestion refers to taking food into the mouth, digestion refers to the breakdown of food in the digestive tract, and excretion refers to the removal of waste products from the body.
