Incorrect statement about the pancreas:

d) It is surrounded by Glissons capsule.

The pancreas is an important gland located in the abdominal cavity, behind the stomach. It plays a crucial role in both the digestive and endocrine systems of the body. Let us discuss each statement and explain why option D is incorrect.

a) It is a compound gland as it has both exocrine and endocrine parts.

The pancreas is indeed a compound gland as it consists of both exocrine and endocrine components.

- Exocrine part: The exocrine part of the pancreas secretes pancreatic juice, which contains digestive enzymes. These enzymes help in the breakdown of carbohydrates, proteins, and fats in the small intestine. The pancreatic juice is alkaline in nature, which helps neutralize the acidic chyme coming from the stomach.

- Endocrine part: The endocrine part of the pancreas consists of small clusters of cells called islets of Langerhans. These islets contain different types of cells, including alpha cells and beta cells. The alpha cells secrete the hormone glucagon, which helps increase blood glucose levels. The beta cells, on the other hand, produce the hormone insulin, which helps lower blood glucose levels. Therefore, the endocrine part of the pancreas is responsible for regulating blood sugar levels.

b) Exocrine part secretes alkaline pancreatic juice having enzymes.

This statement is correct. The exocrine part of the pancreas secretes pancreatic juice, which is alkaline in nature. The alkaline nature of the pancreatic juice helps in neutralizing the acidic chyme from the stomach. Pancreatic juice contains various enzymes, such as amylase, lipase, and proteases, which aid in the digestion of carbohydrates, fats, and proteins, respectively.

c) Endocrine part secretes hormones like insulin and glucagon.

This statement is also correct. The endocrine part of the pancreas, specifically the islets of Langerhans, secretes hormones like insulin and glucagon. Insulin helps in the uptake and storage of glucose by cells, thereby lowering blood glucose levels. Glucagon, on the other hand, stimulates the release of glucose from glycogen stores in the liver, which increases blood glucose levels.

d) It is surrounded by Glissons capsule.

This statement is incorrect. The pancreas is not surrounded by Glissons capsule. Glissons capsule, also known as the capsule of the liver, is a thin connective tissue covering that surrounds the liver. It acts as a protective layer for the liver, but it does not surround the pancreas.

In conclusion, the incorrect statement about the pancreas is option d) "It is surrounded by Glissons capsule." The pancreas is a compound gland with both exocrine and endocrine parts, and it does not have Glissons capsule surrounding it.
