Final answer:
The gallbladder's primary function is to store and concentrate bile produced by the liver, releasing it into the small intestine to aid in fat digestion.
Step-by-step explanation:
The gallbladder is a small, pouch-like organ that has a very specific and important role in the human digestive system. Its main function is to store and concentrate bile, which is a fluid produced by the liver that helps in the process of digesting fats.
Bile contains bile salts and phospholipids that emulsify fats, breaking down large lipid globules into tiny droplets that are easier to digest. When chyme, particularly that high in fatty acids, enters the duodenum from the stomach, the gallbladder releases the concentrated bile into the small intestine via the cystic duct, aiding in the digestion and absorption of fat. The gallbladder is a small organ that aids the liver by storing and concentrating bile. When chyme containing fatty acids enters the duodenum, the bile is secreted from the gallbladder into the duodenum.
