Biology KS3 & KS4: Human circulatory and digestive system

This short film offers a look at respiration and a tour around the circulatory system and digestive system in the human body, through blood vessels and into mitochondria.

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.

This short film is from the BBC series, Inside the Human Body.

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.
