Final answer:
The gallbladder stores and concentrates bile for digestion, releasing it into the duodenum. It is connected to the liver via the common bile duct.
Step-by-step explanation:
The gallbladder is a small organ that aids the liver by storing and concentrating bile. When chyme containing fatty acids enters the duodenum, the gallbladder releases bile into the duodenum to aid in the digestion and absorption of fats.
The gallbladder is connected to the liver via the common bile duct. Bile produced by the liver flows through the ducts, and if bile is needed to digest a meal, it is released into the duodenum. If digestion is not taking place, the bile goes to the gallbladder for storage until the next meal.
