The gallbladder's main function is to store bile, which helps the body break down and digest fats that you eat.
"The gallbladder is part of the biliary system, which serves as the storage reservoir for the bile,".
"It does not produce the bile, but it stores the bile that is currently not being used by the body."
The liver produces bile, which flows through the bile ducts and into the gallbladder,
After a meal, bile is released by the gallbladder when the small intestine secretes a hormone called cholecystokinin.
Then the bile flows into the small intestine and helps to break down fats — for example, that big cheeseburger you just ate.
