Which of the following is the structural and function unit of the largest digestive gland?

Liver is the largest digestive gland. Hepatic lobules are the structural and functional unit of liver. Liver is basically an organ of homeostasis. Which controls many metabolic activities essential for maintaining constant blood composition.

Kupffer cells (present in the lining of blood spaces of liver) are phagocytic and involved in the breakdown of old red blood cells and ingestion of potentially harmful bacteria. Glissons capsule is a thin layer of dense connective tissue which surrounds the liver lobule enclosing branches of portal vein, the hepatic artery, the bile duct and lymphatic capsule. Crypts of Lieberkuhn (present in the intestine) are tubular invagination of the epithelium around the villi, lined largely with younger epithelial cells which are involved primarily in secretion.
