Description

If you have ever wanted to know more about how the body's digestive system works then this course will teach you all about it. It begins by introducing the energy cycle, discussing how energy from the sun is taken through the food chain and then through our bodies. The course then takes you through various different food groups and the substances they contain before guiding you through the various elements of the digestive system in humans.


The course then goes into detail about the digestive system, looking at each stage from ingestion to swallowing and how food is temporarily stored in our stomachs. It looks in detail at the function of each part of the stomach before moving on to discuss how food is primarily digested in the small intestine. The course then goes on to discuss how substances from the food are absorbed into our bodies.


Finally, the course talks about the elimination of waste materials which cannot be digested by our bodies, as well as discussing the reticuloendothelial system. Whether you want to study the digestive system as part of a wider course of biological study or just to learn more about how our bodies work, this course teaches you how we turn food into the energy we need to survive, so make sure you start learning today.
