explain alpha and beta cell
Answers
Answer:
Alpha cells (A cells) secrete the hormone glucagon. Beta cells (B cells) produce insulin and are the most abundant of the islet cells. Delta cells (D cells) secrete the hormone somatostatin, which is also produced by a number of other endocrine cells in the body.
Answer:
The key difference between Alpha and Beta cells is that the Alpha cells (or A cells) produce and secrete glucagon hormone whereas the Beta cells (or B cells) produce and secrete insulin hormone.
The pancreas is one of the major organs located in the abdomen of our body. Pancreas fulfils two major functions namely endocrine (regulation of blood sugar) and exocrine (digestion of foods) functions. Exocrine pancreas secretes essential enzymes such as pepsin, trypsin, chymotrypsin, amylase, lipase, etc. that aid in the digestion of foods we consume. The endocrine pancreas has cells that produce and secrete hormones such as glucagon, insulin, somatostatin, etc. These cells exist as small cell clusters called islets. There are roughly one million islets in human pancreas. Pancreas islets have three types of cells that produce different endocrine products. They are alpha cells (A cells), beta cells (B cells) and delta cells (D cells).
