PHYSIOLOGICAL ROLES OF THE LIVER AND PANCREAS: INTEGRATED METABOLIC, SECRETORY, AND REGULATORY FUNCTIONS IN HUMAN HOMEOSTASIS
Keywords:
liver physiology, pancreas physiology, hepatic glucose metabolism, glycogen synthesis, gluconeogenesis, bile acids, CYP7A1, insulin secretion, GSIS, glucagon, GLP-1, incretin axis, hepatopancreatic axis, metabolic homeostasis, NAFLDAbstract
he liver and pancreas are anatomically adjacent, developmentally related, and functionally inseparable organs that together orchestrate the central metabolic, digestive, endocrine, and detoxification functions essential to human homeostasis. The liver performs over 500 distinct physiological functions including glucose buffering, lipoprotein metabolism, plasma protein synthesis, bile acid production, and xenobiotic biotransformation. The pancreas provides both exocrine digestive enzyme secretion and endocrine glucose-insulin regulation through its acinar and islet cell compartments.
