Referring to something not involved in or relating to the process of digestion. It describes substances, activities, or systems that do not contribute to the breakdown and absorption of food within the body. This encompasses aspects outside the digestive tract's scope, or processes unrelated to nutrient breakdown. Primarily, it relates to elements, systems, or actions not directly facilitating the physical and chemical alteration of ingested materials for nutrient extraction and utilization. These include processes like absorption, excretion, and other bodily functions that support metabolism but don't directly digest food.
Non-digestive meaning with examples
