👉 In medicine, a gallbladder is a organ located in the upper right quadrant of the abdomen. It is an important part of the digestive system and plays a crucial role in digestion by secreting bile which helps to break down fat into smaller particles that can be absorbed into the bloodstream. Gavials are small pouches within the gallbladder that contain bile, which serves as a natural lubricant for the gallbladder and prevents it from bulging or protruding.
