What is the function of the gallbladder in the digestive system?

The gallbladder plays a crucial role in the digestive system by storing bile, which is produced by the liver. Bile is a substance that aids in the digestion and absorption of fats. When you eat a meal that contains fats, the gallbladder contracts and releases stored bile into the small intestine, where it helps emulsify fats, allowing for easier digestion by enzymes.

Storage of bile is essential because the liver constantly produces bile, but it is not always needed immediately. The gallbladder allows for a concentrated supply of bile to be available when food enters the small intestine, facilitating efficient digestion. This specialized function is distinct from processes like enzyme production, nutrient absorption, or hormone secretion, which are carried out by different organs in the digestive system. Thus, the gallbladder's primary function is to store bile, making it readily available for the digestive process when needed.
