Which of the following is a function of gall bladder.

Options

A. Deamination
B. Bile storage
C. Synthesis of plasma protein
D. Storage of fat soluble vitamin

Answer

### Step-by-Step Solution:

1. **Understanding the Gallbladder**: The gallbladder is a small organ located beneath the liver that plays a crucial role in digestion, particularly in the processing of fats.

2. **Primary Function of the Gallbladder**: The main function of the gallbladder is to store and concentrate bile, which is produced by the liver. Bile is essential for the digestion and absorption of fats in the small intestine.

3. **Response to Hormones**: The gallbladder responds to intestinal hormones, such as cholecystokinin (CCK), which triggers the gallbladder to contract and release bile into the small intestine when fatty foods are consumed.

4. **Regulating Bile Composition**: The gallbladder also contributes to regulating the composition of bile, ensuring that it is effective for digestion.

5. **Controlling Bile Flow**: It controls the flow of bile into the small intestine, ensuring that bile is released at the right time and in the right amounts.

6. **Contraction and Secretion**: The gallbladder contracts to secrete bile into the bile duct, which then leads to the duodenum (the first part of the small intestine).

7. **Evaluating Options**: Given the functions discussed, we can evaluate the options provided in the question:
- Diminution: Not a function of the gallbladder.
- Bile storage: Yes, this is a primary function of the gallbladder.
- Synthesis of plasma proteins: Not a function of the gallbladder.
- Storage of fat-soluble vitamins: Not a function of the gallbladder.

8. **Conclusion**: The correct answer to the question is that the gallbladder's function is bile storage.
