Journeys: Liver. Stop 2

Filter

Blood flows through the liver. Catch the grey rubbish in all three streams, and let the yellow food go by!

The liver cleans the blood like a filter.

That's food, and the body needs it. Catch the grey rubbish.

The liver makes the rubbish safe, and it leaves the body. This is a real liver under a microscope.

Some rubbish slipped through! Catch it faster.
