PANCREAS :
• Has both exocrine and endocrine function.
• Contains about 1-2 million islets of langerhans which has glucagon secreting α-cells and insulin secreting β-cells.
• Glucagon : Peptide hormone, stimulates glycogenolysis by acting on liver cells. Also, stimulates gluconeogenesis. Hence called hyperglycemic hormone.
• Insulin : Peptide hormone, acts on hepatocytes and adipocytes to enhance cellular glucose uptake, stimulates conversion of glucose to glycogen (glycogenesis), so decreases blood glucose level called hypoglycemic hormone.
• Deficiency of insulin causes diabetes mellitus in which loss of glucose occurs through urine.
