Anatomy Of The Gall Bladder

By Edited Nov 13, 2013 0 0

Human gallbladder anatomy
The gall bladder anatomy play a vital role in the digestive system. It is an organ that can be found just below the liver. It measures about 3 inches when it comes to length and about 1.6 inches when it comes to diameter as it is distended fully. It is small and pear shaped. There are actually three parts of the gall bladder known as the fundus, the neck and lastly, the body. The neck of gall bladder is the one that connects to the cystic duct through which the gall bladder can be linked to the biliary tree.  The gall bladder has a fold at its neck known as the Hartmann’s pouch where the gallstones can be usually found.. The gall bladder is specifically located in the angle between the lateral margin of the abdominal muscle known as the rectus abdominis and the costal margin.

The Layers Of The Gall Bladder

Gallbladder layers of tissues

The gall bladder is made up of different layers of tissues. The inner most layer of the gall bladder is known as the epithelium which is a thin sheet of groups of cells. The epithelium is known to be the one closest to the center of the gall bladder. The next thin layer is known as the lamina propria which is characterized as a loose connective tissue. If you join the epithelium together with the lamina propria, it will be known as the mucosa. The next layer of tissue is made up of smooth muscular tissues that serve to promote contraction of the bladder, allowing the bile to be transported into the bile duct. This layer is known as the muscularis tissue. Surrounding this layer of muscle is another layer of fibrous tissue knownb as the perimuscular fibrous tissue. From the word itself, perimuscular means around the muscle. Lastly, the outer most covering or layer of the gall bladder is known as the serosa. The serosa comes from the peritoneum that is lining the abdominal cavity. The other abdominal organs have their own muscularis mucosae layer making the gall bladder a unique abdominal organ because it does not have the said layer.

The Important Functions Of The Gall Bladder

Helps process digestion

Your gall bladder serves an important function in the process of digestion. When you eat food that contains a significant amount of fat, cholecystokinin or CCK is stimulated to be released from the digestive tract. When the CCK or cholecystokininis released the bile stored in the gall bladder is eventuallly released to the duodenum. Bile is actually produced in the liver but then it is stored in your gall bladder and released till it is needed by the digestive system for the metabolism and processing of taken fats with food. Bile is important because it emulsifies the fats in the digested food.

Gall bladder does not simply store the bile and releases it when needed. It also allows increased concentration of the bile for it to be able to become more effective in emulsifying fats later on. Aside from being able to emulsify fats allowing it to be digested very well, the bile is also responsible for neutralizing acids in foods that are partly digested. If you are wondering what the passage way from the gall bladder is, it usually begins flowing into the cystic duct. From there, it will go through the common bile duct and then lastly into the part of the small intestine considered to be its destination known as the duodenum.

The body normally produces and stores about 1000 to 1500 ml of bile every day. This is continuously produced by the body to aid in the digestion of fats. The gall bladder should be maintained in normal function for it to be able to release adequate amount of bile needed by the digestive system. Neurochemical signals which occur once the body takes in fatty foods signals the gall bladder to contract and release the needed amount of bile.

Problems Associated With Gall Bladder

Gall stone formation

There are different disease conditions that can be associated with the gall bladder. There are instances wherein the contents of the bile tend to crystallize in the gallbladder which leads to the formation of gall stones. These gall stones are hard in consistency and usually appear in persons about forty years old and above. These are also common in women especially for those who are obese. Once there are gall stone formations, there is a great tendency that such concretions will block the pathway of the bile going to your small intestine. When this happens, your bile will eventually be inflamed and you will have difficulty when it comes to the digestion of fats from the food you take. Once your gall bladder is inflamed, you will feel symptoms that are similar to indigestion usually experienced every time you take a high fat meal. This can include severe pain which is attributed to the obstruction brought about by the gall stones. Gall stones can vary in size and consistency and usually, if they are just small, they can easily be treated with medications thus they can easily be eliminated from the body through urine. In cases when it is already too large to pass out, surgical intervention becomes necessary.

 

Cholecystectomy

Cholecystectomy removal of the gallbladder

If the complication becomes severe and the gall stones cause much damage to the bladder, there is the necessity to remove the bladder through surgical means. This is known as cholecystectomy primarily removal of the gall bladder. In this procedure, about five to eight inch cut is made through the abdomen through which your gall bladder will be taken out once it is removed. When the gall bladder is removed, bile still reaches its destination in the small intestine because it is directly delivered from liver ducts to the duodenum.

These details simply go to show that even if it is just a small organ, the gall bladder serves important functions that should never be neglected. The gall bladder works well with the digestive system so that you can easily process the food that your eat most especially fats.
