Digestive system mouth to anus

A look at the time it takes for food to pass through the gut from mouth to anus. In a healthy adult, transit time is about 24—72 hours. Read the article The human digestive system for further information. Digestive activity begins with the sights, sounds and smells of food. Just looking at or smelling appetising food can result in the brain sending signals to the salivary glands to make the mouth water and to the stomach to secrete gastric juice.

Digestive System

We need food to fuel our bodies for energy, growth and repair. The digestive system converts the foods we eat into their simplest forms, like glucose sugars , amino acids that make up protein or fatty acids that make up fats. The broken-down food is then absorbed into the bloodstream from the small intestine and the nutrients are carried to each cell in the body. The digestive tract begins at the mouth and ends at the anus.
