Ketogenesis: Ketogenesis occurs in the liver when carbohydrate intake is low, producing ketone bodies from fatty acids to provide an alternative energy source for tissues like the brain and muscles.
Gallbladder: The gallbladder stores and concentrates bile produced by the liver, releasing it into the small intestine to aid in the digestion and absorption of fats.
Hepatic Portal Vein System: The hepatic portal vein collects nutrient-rich blood from the gastrointestinal tract and transports it to the liver for processing before it enters general circulation.
