Question

Explain the structure and function of pancreas.

Answer 1

Pancreas is situated behind the stomach. It has four types of cells such as - Alpha-cells (20%) Beta-cells (70%) Delta-cells (5%) P.P. cells or F-cells (5%). It secretes several hormones such as:

1. Glucagon - Stimulates liver to convert glycogen into glucose.
2. Insulin Stimulates liver to convert excess blood glucose into glycogen.
3. Somatostatin - Controls levels of insulin and glucagon.

Pancreatic Polypeptide - Controls movements of intestine and thereby glucose absorption and controls secretion of pancreatic juice.
