The liver is elongate and is divided into several separate lobes. A characteristic of snakes is that there is a relatively long distance between the caudal tip of the liver and the gall bladder. Snakes have a well-developed gall bladder adjacent to the duodenum and caudal to the liver. Multiple bile ducts pass from the gall bladder, through the pancreas, into the duodenum. In most species, the gall bladder, pancreas and spleen are closely associated. In some snakes the pancreas may be fused with the spleen forming the splenopancreas.

==Cloaca==

==Cloaca==

The [[Cloaca|cloaca]] is divided into three parts (cranial to caudal): coprodeum, urodeum and proctodeum.  The coprodeum collects faeces from the colon. The urodeum, which is the midsection of the [[Cloaca|cloaca]], collects urinary waste and products of [[Snake Reproductive System|reproduction]]. The urogenital papilla is situated dorsally behind a small fold. The proctodeum is the reservoir for faecal and urinary waste before [[Lizard and Snake Excretion|excretion]] and contains the openings of the cloacal scent glands.
