In addition to its usefulness as a receptacle, the average human stomach has a volume of about 1.5 liters which can be used to store liquids for a short period of time. The conversion from foodstuffs into liquid form is facilitated by enzymes that break down large molecules into simpler ones and then absorb them into individual cells through “pumping” or active transport across cell membranes.” This basically means there’s all this liquid in your stomach contained in these pumps, so when you digest things it really creates liquid! These cells will pump out liquid containing water and sugars like glucose at up to an order of magnitude greater than any other substance without much difference between various foods.”
