Abstract
The hepatobiliary system comprises the liver, gallbladder, and bile ducts, playing a crucial role in digestion and metabolism. The liver is the largest gland in the body, divided into lobes and supported by ligaments. Its histological structure includes hepatocytes, bile canaliculi, and sinusoids, which facilitate metabolic and detoxification functions. The gallbladder stores bile, and the bile ducts transport it to the duodenum, aiding in fat digestion. This system's anatomy and histology are essential for understanding its physiological and pathological conditions.
