Your guide to Bubble Works
On the hill above the small intestine stands Bubble Works: the liver, which makes bile all day, and the gallbladder, a small pear-shaped pouch tucked underneath that stores it and makes it stronger by taking out water.
When a meal with fat in it arrives, the gallbladder squeezes and bile flows down a duct into the small intestine. Bile salts break fat into tiny droplets, so lipase has more surface to cut. Bile doesn’t cut anything itself, which is why it isn’t an enzyme.
Bile is made in the liver and stored in the gallbladder. It’s a soap for fat, not an enzyme.
Bile salts have a side that likes water and a side that likes fat. That’s exactly how soap works.
Locals and staff
