What this game teaches
Knowing roughly how a system is meant to work makes it far easier to describe a problem accurately, and an accurate description is one of the most useful things you can bring to an appointment.
The questions link structure to everyday experience — why the kidneys matter for blood pressure, why the gut affects more than digestion, what the immune system is actually doing when you feel unwell.
It is also useful groundwork for reading our condition pages, which assume a little of this and explain the rest.
