Which of following, statement is false about pancreas ?

Options

A. Pancreas acts as both exocrine and endocrine glands
B. Endocrine pancreas consists of “lslets of Langerthans “
C. There are about 1 – 2 million lslets of Langerthans representing only `1 – 2%` of pancreatic tissus
D. Pancreas secretes only insulin

Answer

To determine which statement is false about the pancreas, we need to analyze each statement provided in the video transcript.

### Step-by-Step Solution:

1. **Understanding the Functions of the Pancreas**:
- The pancreas serves both exocrine and endocrine functions. The exocrine part produces digestive enzymes, while the endocrine part regulates blood sugar levels through hormones.

2. **Islets of Langerhans**:
- The pancreas contains clusters of cells known as the Islets of Langerhans, which include alpha cells and beta cells. Alpha cells produce glucagon, and beta cells produce insulin.

3. **Hormonal Secretion**:
- Alpha cells secrete glucagon, which raises blood glucose levels, while beta cells secrete insulin, which lowers blood glucose levels. This is a fundamental aspect of glucose metabolism.

4. **Proportion of Islets**:
- It is mentioned that there are about 1-2 million Islets of Langerhans, which represent only 1-2% of the total pancreatic tissue. This statement is accurate.

5. **Evaluating the False Statement**:
- The last statement claims that the pancreas "secretes only insulin and glucagon" from alpha cells. This is false because insulin is secreted by beta cells, not alpha cells. Alpha cells only secrete glucagon.

### Conclusion:
The false statement about the pancreas is that it "secretes only insulin and glucagon from alpha cells."
