Digestion: The journey of food in the digestive tract!

Food entering the digestive tract is chewed, ground, broken down and converted to nutrients that enable the body to perform all its functions. At the end of this journey, which lasts more than 24 hours, the body expels everything it has not used. Farts, rumbles and burps are signs that your body is working properly.

4.1 The organs in the digestive tract

What are the components of the digestive system?

The digestive system, comprising the digestive tract and its accessory glands, breaks down and absorbs food. As food journeys through the digestive tract, it passes one segment after another, each fulfilling a particular function. The enteric nervous system, also known as the ‘abdominal brain’, orchestrates all these functions.

4.2 The stages of digestion

The different stages of digestion, step by step!

In this course, we explore the sequence of mechanical and chemical processes that gradually transform the food into simpler elements: nutrients. The organism then absorbs them in order to assimilate them.

4.3 Historical representations of digestion

Digestion: From Galen’s discoveries to the present day.

From Galen’s description to the 17th-century mechanical model, scientific developments throughout history have enabled us to build up our current knowledge of digestion.

4.4 Digestive phenomena

All there is to know about diarrhoea, rumbling stomachs, farts and burps!

The annoyances we sometimes experience, such as diarrhoea, hiccups and belching, may be embarrassing, but they are part of the normal functions of the digestive tract. We will explore what causes them.
