Textbook Question

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

Verified step by step guidance

Step 1: Begin by understanding the function of the gallbladder. The gallbladder is a small, pear-shaped organ located beneath the liver. Its primary role is related to bile, a digestive fluid produced by the liver.

Step 2: Clarify the production of bile. Bile is not produced by the gallbladder; it is synthesized by the liver. The gallbladder stores and concentrates bile until it is needed for digestion.

Step 3: Examine the anatomical relationship between the gallbladder and the pancreas. While the gallbladder is not directly attached to the pancreas, both organs are part of the digestive system and work together during digestion.

Step 4: Understand the role of secretin. Secretin is a hormone produced by the small intestine, not the gallbladder. It stimulates the pancreas to release bicarbonate-rich fluids to neutralize stomach acid.

Step 5: Conclude that the correct function of the gallbladder is to store and concentrate bile, making option 'c' the most accurate description of its role.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Gallbladder Function

The gallbladder is a small organ that plays a crucial role in digestion by storing and concentrating bile, which is produced by the liver. Bile aids in the emulsification and absorption of fats in the small intestine. Understanding this function is essential for recognizing the gallbladder's importance in the digestive system.

Bile Production

Bile is a digestive fluid produced by the liver that contains bile salts, cholesterol, and bilirubin. It is essential for the digestion and absorption of dietary fats. The gallbladder does not produce bile; instead, it stores bile produced by the liver until it is needed for digestion.

Anatomy of the Digestive System

The anatomy of the digestive system includes various organs that work together to process food. The gallbladder is located beneath the liver and is connected to the small intestine via the bile ducts. Understanding the anatomical relationships between these organs helps clarify the gallbladder's role in digestion and its interactions with other digestive organs.
