PATHOLOGY

Detailed explanation-1: -The -cells secrete glucagon as a response to low blood glucose. The major function of glucagon is to release glucose from the glycogen stores in the liver.

Detailed explanation-2: -While the beta cell produces insulin, the only blood glucose-lowering hormone of the body, the alpha cell releases glucagon, which elevates blood glucose. Under physiological conditions, these two cell types affect each other in a paracrine manner.

Detailed explanation-3: -Alpha cells ( cells) are endocrine cells that are found in the Islets of Langerhans in the pancreas. Alpha cells secrete the peptide hormone glucagon in order to increase glucose levels in the blood stream. Pancreatic islets (islets of Langerhans).

Detailed explanation-4: -Blood glucose homeostasis is mainly achieved by the coordinated function of pancreatic alpha-, beta-, and delta-cells, which secrete glucagon, insulin, and somatostatin, respectively.
