Question

Why pancreas is called both exocrine and endocrine gland?​

Answer 1

The pancreas is termed both an exocrine and endocrine gland because it performs both functions; the endocrine part secretes hormones such as insulin into the bloodstream, while the exocrine part produces digestive enzymes that are secreted into the gastrointestinal tract.

Step-by-step explanation:

The pancreas is a unique organ that serves both endocrine and exocrine functions. The endocrine aspect involves the secretion of hormones such as insulin and glucagon by clusters of cells known as pancreatic islets or islets of Langerhans. These hormones are released directly into the bloodstream to regulate blood glucose levels. In contrast, the exocrine function of the pancreas involves the production of digestive enzymes and bicarbonate by cells called acinar cells. These are excreted into ducts that lead to the gastrointestinal tract, specifically the duodenum, to aid in the digestion of nutrients.

Thus, the pancreas is termed a heterocrine gland, reflecting its dual functionality in the body's hormonal and digestive systems. The exocrine part of the pancreas produces pancreatic juice, which contains enzymes to break down carbohydrates, proteins, and fats. This crucial gland, located near the stomach, plays a significant role in maintaining homeostasis through its exocrine and endocrine activities.

This question is in my stored notes read below

Step-by-step explanation:

Pancreas is an exocrine gland as it has a duct to store pancreatic juice secreted by the pancreas and use it whenever required. It is considered as a endocrine gland as it does not have a duct to store the hormones insulin and glucagon which are directly supplied to the blood stream.
