The gallbladder's primary function is to store bile, which is produced by the liver and plays a crucial role in the digestion and absorption of fats. When food high in fat enters the small intestine, the gallbladder contracts and releases bile into the digestive tract to facilitate the breakdown of those fats. This process is essential for proper digestion and contributes to nutrient absorption.

In contrast to the role of the gallbladder, regulating blood sugar levels is primarily managed by the pancreas and its production of insulin and glucagon. Filtering toxins from the blood is a function of the liver and kidneys, rather than the gallbladder. The gallbladder does not regularly refill and empty with digested food; rather, it releases bile in response to the presence of fats in the intestine. Understanding the specific function of the gallbladder clarifies why its role in storing bile is critical for digestion.
