Biology KS3/4: Human circulatory and digestive system

A look at respiration and a tour around the circulatory system and digestive system.

Using detailed CGI images, it takes the student inside blood vessels.

There is a detailed description of red blood cells and their journey around the body including the way that they are adapted to carry oxygen.

It also has up-close images of mitochondria and the villi inside the small intestine.

Teacher Notes

Students could make models of red blood cells in capillaries or of mitochondria.

Alternatively, they could draw a journey to the mitochondria for two characters - an oxygen atom and a glucose molecule.
