Question

Mention the exact location of the following:
Islets of Langerhans.

Answer 1

Hint: This organ is surrounded by the liver, small intestine and spleen, among other organs. It is spongy, about 6 to 10 inches in thickness, shaped like a flat pear or a fish draped over the belly.

Complete answer:
The pancreas is an abdominal organ. The pancreas is surrounded by the spleen, liver, and small intestine, among other organs. It is spongy, about 6 to 10 inches in thickness, shaped like a flat pear or a fish draped over the belly. It is present in the middle of the abdomen, called the pancreas head. On the intersection of the stomach the head of the pancreas meets the first section of the intestine. This is where the stomach partly digested food is pumped into the intestine and the pancreas secretes digestive enzymes. The pancreas plays a crucial part in translating the food we ingest into fuel for cells of the body. The pancreas has two major functions, one which helps to digest and one which controls blood sugar.
The islets of Langerhans are a cluster of cells in the pancreas which generate and release hormones that regulate the level of glucose. These three-dimensional clusters are composed of about 1000 pancreatic cells, and each islet has a diameter of approximately 50–500 micrometer. The islets of Langerhans are the cellular components of the endocrine pancreas which perform an important part in the management of glucose homeostasis. Therefore, we can say that the islets of Langerhans are found in the pancreas.

Note: The islets of Langerhans are micro-organ with at least four distinct groups of endocrine cells found within the pancreas. The islets of Langerhans are the cellular components of the endocrine pancreas which perform an important part in the management of glucose homeostasis.
