Final answer:
The right subhepatic space, also known as Morison's pouch, is located between the liver and the right kidney. It is anatomically related to the gallbladder, which releases bile into the duodenum, and is in close proximity to the right colic flexure and lesser omentum.
Step-by-step explanation:
The right subhepatic space, also known as Morison's pouch, is the anatomical space between the liver and the right kidney. When the gallbladder, which is a muscular sac nestled in a shallow area on the posterior aspect of the right lobe of the liver, contracts, it releases bile into the duodenum via the common bile duct. The liver itself is divided into lobes and connected to various structures by peritoneal folds known as ligaments. One of these structures, the right colic flexure (also, hepatic flexure), is found at the inferior surface of the liver, where the ascending colon turns to become the transverse colon. The lesser omentum is significant as it connects the liver to the lesser curvature of the stomach, playing a role in the structural integrity of these organs and the peritoneal cavity's layout.
