After the mushed up food comes out of your stomach through your pylorus, it goes into your duodenum.
Your duodenum helps mush up your food some more using special chemicals, it tells the pylorus when to close up and not let too much food through.
It also connects to other parts of your digestive system like your liver, gall bladder and pancreas.
Those parts of your body let out liquids and chemicals that help break your food up.
