Your guide to The Tool Shed
The pancreas is a long gland tucked behind the stomach. Its digestive side makes the heavy-duty tools: proteases for protein, amylase for starch and lipase for fat, in more than a litre of pancreatic juice a day.
It also mixes in bicarbonate, which neutralises the acid coming out of Acid Lake so the tools can work. And the proteases leave the shed switched off, with their safety guards on. They only switch on in the small intestine, so they don’t snip the shed.
Your pancreas makes protease, amylase and lipase and sends them to the small intestine, with bicarbonate to calm the acid.
Not every tool is from the shed: lactase lives on the small intestine’s lining, and bile comes from Bubble Works.
Locals and staff
No microbes work here. The tools are proteins, not crew.

The small intestine. Villi make about 30 m² of surface. Most digestion and absorption happen here.
