This is a topic that many people are looking for. voteyesons.org is a channel providing useful information about learning, life, digital marketing and online courses …. it will help you have an overview and solid multi-faceted knowledge . Today, voteyesons.org would like to introduce to you Gallbladder – Definition, Function & Location – Human Anatomy | Kenhub. Following along are instructions in the video below:
There its matt from kenhub and the focus of this short tutorial is the the gallbladder which you see here highlighted in green. We are going to talk about location function parts lymphatic drainage vascular system and nervous supply. The gallbladder is a small green intraperitoneal sac that lies in the fossa between the left.
And right hepatic lobes at the level of the right ninth rib. Wait youre thinking did he just say. Green yes.
Its actually green in color due to the bile that it stores. And because you probably missed this part. Ill say it again the gallbladder lies in the fossa between the right and left lobes of the liver to which it is directly connected to via the fibrous capsule.
The gallbladder functions as an accessory organ to the foregut it stores and concentrates bile that is created by the liver and it systematically drains bile into the duodenum via the common bile duct aiding in digestion and fat absorption. There are three main parts to the gallbladder. The fundus of the gallbladder.
The fundus is defined as the part of a hollow organ that is farthest away from the opening. It can be found at the level of the ninth costal cartilage and can be seen to slightly protrude from under the inferior aspect of the liver. Just superior to the transverse colon.
You see it highlighted here in green and here in yellow as it lies without the liver being retracted now highlighted in green is the body of the gallbladder. Which lies under the cover of the liver anteriorly. But is also in contact with the transverse colon inferiorly and the duodenum posteriorly lastly.
The neck of the gallbladder is bent into an s shape. So it is able to join the cystic duct here bile begins its journey away from the gallbladder through a series of ducts to join with the contents of the pancreas and together work their magic on the digested stomach contents on a molecular level. The cystic duct is opened and closed via the spiral valve.
Which is made by the mucosa that surrounds it in a spiral formation the common bile duct is formed via the merger of the cystic duct and the common hepatic duct. It merges with the main pancreatic duct to form the hepatopancreatic ampulla. Which enters.
The second part of the duodenum via the major duodenal papilla as mentioned earlier the common bile duct functions to drain bile from the gallbladder into the duodenum blood is brought to the gallbladder via the cystic artery seen here in green which stems from the right hepatic artery. It is collected by the cystic veins of which some drain the neck and biliary ducts and empty into the portal vein. Seen here in green.
While others drain. The body and the fundus and after empty back into the liver. The hepatic nodes are responsible for the lymphatic drainage of the region innervation of the gallbladder consists of sympathetic fibers from the celiac plexus parasympathetic fibers from the vagus nerve.
Highlighted here in green and sensory fibers from the right phrenic nerve. Which you now see in green. This video is more.
Fun. Than reading. A textbook right.
