Where are the islets of Langerhans located?

The islets of Langerhans are specialized clusters of cells found within the pancreas. These structures play a crucial role in regulating blood glucose levels by producing hormones such as insulin and glucagon. Insulin lowers blood glucose levels, while glucagon raises them, working together to maintain homeostasis in blood sugar levels.

The pancreas itself is an organ that has both exocrine functions (like producing digestive enzymes) and endocrine functions (like hormone secretion). The islets of Langerhans specifically consist of different types of cells, including alpha cells, beta cells, and delta cells, each responsible for the secretion of specific hormones that are essential for carbohydrate metabolism and overall energy balance in the body.

The liver, kidneys, and adrenal glands each have distinct functions and structures. The liver is primarily involved in processing nutrients and detoxifying substances, the kidneys are vital for filtering blood and producing urine, and the adrenal glands produce hormones related to stress response and metabolism. These organs do not contain the islets of Langerhans, which are unique to the pancreas.
