Hello all I'm Glenn Fox
and in this video
I'll discuss the biliary tract my objectives for this video are for you to understand
the drainage pattern of bile and the
structure of the gallbladder
Bile is produced in the liver and
That bile is drained from the liver through the hepatic ducts
There's a right and a left hepatic duct
These hepatic ducts unite to form the common hepatic duct, which can conduct bile down to the cystic duct
Where it can be stored for later release by the gallbladder a
Continuation of
the junction of common hepatic duct, and the cystic duct is
known as the bile duct or the common bile duct, which
descends down in the hepatoduodenal and
Is joined by the pancreatic duct to form this dilation
Called the hepatic pancreatic. Ampulla that hepatopancreatic ampulla
moves through the major duodenum papilla where these secretions are released into the second or
descending part of the duodenum
Shown here are the contents of the hepatoduodenal ligament keeping in mind that hepatoduodenal ligament is going to
Connect the liver adjacent to the gallbladder
with the duodenum and the
three major
Constituents of this hepatoduodenal ligament are the bile duct or the common bile duct
the
hepatic artery proper (HAP)
which then divides into
the left and the right branches of the hepatic artery proper
As well as the hepatic portal vein
which is drained all of the blood from the gastrointestinal tract and
Delivering it to the liver for processing
The gallbladder
sits in close association with
the right
Anatomical lobe of the liver and it can be found
inferior to this right lobe
The gall bladders role is to store bile conducted
Through the common hepatic duct and cystic duct from the liver
which is why oftentimes the
gallbladder in cadaveric
Specimens is stained green
The gallbladder has a fundus although an anatomical position. That fundus is inferior a
body
And
a neck and
It's supplied by the Cystic artery
the Cystic artery is
typically a branch of
the right branch of the
hepatic artery proper
It may also be
a branch of the hepatic artery proper or a branch of
the gastroduodenal artery or
May find its source from a variety of other vessels
that Cystic artery is
a very important artery to locate
For the removal of the gallbladder and it can reliably be found in the hepatobiliary triangle
That hepatobiliary triangle has the following sides
The superior portion or side is going to be the inferior surface of the liver
the medial portion is
The common hepatic duct
In the inferior
portion running
alongside of the gallbladder is going to be the
cystic duct and so we can see that that Cystic artery regardless of its
Vessel of origination is going to traverse that pata biliary triangle in
terms of its innervation
the gallbladder
Is innervated by the hepatic plexus?
