The gallbladder
a. Produces bile
b. Is attached to the pancreas
c. Stores and concentrates bile
d. Produces secretin

Verified step by step guidance

1. Step 1: Understand the function of the gallbladder in the digestive system. The gallbladder is a small organ located beneath the liver.
2. Step 2: Recall that bile is a digestive fluid produced by the liver, not the gallbladder. The gallbladder's role is related to bile but does not involve its production.
3. Step 3: Consider the anatomical connections. The gallbladder is connected to the liver and the small intestine via bile ducts, but it is not attached to the pancreas.
4. Step 4: Recognize that secretin is a hormone produced by the small intestine, not by the gallbladder.
5. Step 5: Conclude that the gallbladder's primary function is to store and concentrate bile, making option (c) the correct description.

Key Concepts

Function of the Gallbladder

The gallbladder is a small organ that stores and concentrates bile produced by the liver. It releases bile into the small intestine to aid in the digestion and absorption of fats.

Bile Production

Bile is a digestive fluid produced by the liver, not the gallbladder. It contains bile salts that emulsify fats, making them easier to digest.

Anatomical Relationships of the Gallbladder

The gallbladder is attached to the liver, not the pancreas. It connects to the bile ducts that lead to the small intestine, facilitating bile flow during digestion.
