👉 Ingestion is a concept in biology, specifically within the field of nutrition. It refers to the process by which food enters and is absorbed into the body through the digestive system. The ingestion of food typically involves the mouth, where it first begins its journey down the esophagus, then flows into the stomach, where it is broken down further for absorption in the small intestine. Ingestion can be divided into two main types: oral ingestion and enteral (or intravenous) ingestion.
