# 2.3 The body's different systems

The body has a variety of different internal systems such as the skeleton, the collection of muscles, and the network of arteries and veins. To understand properly how the body works, we need to understand these separate systems as well as the links between them.

## Discussion

Did you find this interesting? Did you know about all these systems already or was there something new? This interactive diagram looks at the body by dividing it up into systems that each have specific purposes, such as breathing, moving, or thinking. Although we can look at these systems separately it is worth noting that they have to work together to make our bodies work.

Each of these systems is very interesting and there is much to learn about them. For the rest of this course we will be concentrating on the cardio-respiratory system.
