What is the significance of hepatorenal pouch of Morrison -

Ans. is 'a' i.e., It is the most dependent space in the abdomen and fluid from ascites first accumulates here o The posterior right subhepatic space (also known as the hepatorenal fossa or Morison pouch) separates the liver from the right kidney. It is a potential space that is not filled with any fluid in normal conditions -Gross anatomy# Posterior right subhepatic space is a subcompartment of the supramesocolic spaceand is separated from the anterior right subhepatic space by the transverse mesocolon.Boundaries# The recess is bounded :o Anteriorly: right lobe of the liver and gallbladdero Posteriorly: superior aspect right kidney; right adrenal gland; second part of theduodenum; hepatic flexure; pancreatic heado Superiorly: transverse mesocolonCommunications# The posterior right subhepatic space communicates with the right subphrenic spaceand right paracolic gutter. The subhepatic space communicates with the lesser sac via the foramen of Winslow.Related pathology# Fluid (e.g. ascites or haemoperitoneum) accumulates here as it is the lowest dependent spaces of the peritoneal cavity from a wide range of causes. It is also a preferential site for metastases and abscesses.
