What Is the Function of the GALLBLADDER – Explore 8 Major Functions
May 31, · The gallbladder is a pear-shaped, hollow structure located under the liver and on the right side of the abdomen. Its primary function is to store and concentrate bile, a . Feb 26, · Your gallbladder is a part of your biliary system, which is made up of your liver, gallbladder, and associated ducts. This system is needed for .
Here we shall learn where the gallbladder is located in the body, along with its functions, and the diseases affecting it. Have a look! The gallbladder is a small, green, pear-shaped organ located in the abdominal cavity of vertebrates.
It grows to a length of 8 centimeters, and has a diameter of 4 centimeters. The function of the gallbladder is to store the bile secreted by the liver.
Its location corresponds to the lowest ribs, on the right side of the rib cage. Would you like to write for us? Well, we're looking for good writers who want to spread the word. Get in touch with us and we'll talk The cystic vein drains the blood into the portal vein. In addition to this, the gallbladder contracts in response to the hormone cholecystokinin secreted by the duodenum.
Fundus : The fundus is the rounded part of the gallbladder that is farthest from the cystic duct, and is covered with peritoneum. Body : The part of the gallbladder between the fundus and the neck, is called the body. The body lies in contact with the undersurface of the liver. Neck gallbladder The neck is the part of the gallbladder that lies closest to the cystic duct, and it connects the body of the gallbladder to shstem cystic gallblarder.
The body and neck of the gallbladder zystem attached to the surface of the liver by the peritoneal covering. The gallbladder is the site for storage and concentration of bile, until it is necessary for digestion. It can store about 50 ml of bile. The primary function of the gallbladder is to aid in the digestion of fats.
To carry out this function, it receives bile secreted by the liver through the cystic duct. The liver secretes bile through the left and right hepatic ducts, which come together to form the common hepatic duct. The cystic duct from the gallbladder joins the common hepatic duct to form the common bile duct, sysgem carries bile to the small intestines. The sphincter of Oddi regulates the flow of bile into the small intestines, and when it contracts, the bile flows through the cystic duct into the gallbladder.
The bile accumulated in the gallbladder undergoes certain modifications. The function of bile is to emulsify the fats present in the partly digested food, and this is essential for the digestion of fats and lipids. When fatty food reaches the small gody, it stimulates the release of a hormone cholecystokinin from the mucous membranes present on the walls of the small intestines. The hormone reaches the gallbladder through the bloodstream, and triggers its contraction.
This hormone also triggers the relaxation of the muscles of the sphincter of Oddi, facilitating the flow of concentrated bile into the small intestines. Gallstones are the most common conditions affecting the gallbladder, and are formed due to the solidification of certain substances present in the bile.
While gallstones are mostly harmless, they can sometimes grow bigger and move into the cystic bbody, causing a blockage. This condition is more common in glalbladder who are above the age of 40 and obese. Also, women are more prone to the condition. A sharp pain in the abdominal region is the most common symptom of gallstones, although a patient may not experience any symptoms for years.
The xystem, if present, worsen after the intake of fatty foods. In most cases, the treatment comprises oral medications that dissolve the gallstones. Lithotripsy, in which ultrasonic shock waves are used to nody the stones gallbladser smaller fragments, is also used. The surgical treatment involves qhat of the gallbladder by a process termed as cholecystectomy. After the surgery, provision how to cook baked apples in the oven made for the bile to what i want to become in future through the ducts directly from the liver to the small intestine.
The surgery is boody and there are rarely any complications involved. In rare cases, however, complications such as bleeding, diarrhea, and infection of the cystic duct, may arise.
However, these are not a cause of concern, and can be easily treated with medications after consulting a doctor. Necessary cookies are absolutely essential for the website to function properly.

8 Major Functions in Detail:
May 05, · Gallbladder (axial view) Within the liver, the endometrial cells that overlap each other to form the hepatocytes also give rise to the intrahepatic biliary system. Communication with the extrahepatic bile ducts marks the completion of the intrahepatic biliary system, which occurs around the 10th gestational week. May 19, · The gallbladder is an organ in the human digestive system. Learn more about its function, location on the body, and conditions that affect the . The biliary system consists of the organs and ducts (bile ducts, gallbladder, and associated structures) that are involved in the production and transportation of bile. The transportation of bile follows this sequence: When the liver cells secrete bile, it is collected by a system of ducts that flow.
The fact that over 20 million individuals have gallstone disease in the US alone fires up a reader to learn about the gallbladder function. A digestive organ , gallbladder performs lots of functions like:. These are just the key points about the purpose of the gallbladder in the human body.
In addition, you will get answers to FAQs about gallbladder function, given at the end. But the story of its functions does not end here. Sometimes, even its disease may be asymptomatic, i. It jumps to prominence when you encounter problems like abdominal pain, nauseated feeling or vomiting, shaking chill accompanied by fever, jaundice, and changes in urine dark colored and bowel movements unexplained diarrhea , etc. Here follows a brief description of the gallbladder function.
A careful read will give you an idea about the role of this tiny organ and its vital importance in the body. The major gallbladder function is to act as a storehouse for bile juice. The bile juice remains here until the need arises in the intestine for the digestion of lipids. The liver is the organ that secretes the hepatic bile.
Did you know? Most of us feel uncomfortably bloated after a heavy meal rich in fats and oil. It highlights the importance of gallbladder function in digestive system. The condition is linked to the proper functioning of this digestive organ.
It is because fats take longer digestive period in comparison with that of proteins and carbohydrates. The breakdown of fat globules in food into simpler particles is essential for multiple reasons. First, larger particles need to be broken down into smaller ones for absorption across the intestinal wall into the bloodstream. Second, it is done for the end that the regular digestive enzymes may act upon them effectively.
This process of breaking down complex fatty substances into simpler molecules is termed as emulsification. This is exactly the function of bile juice that the hepatic cells in the liver secrete. Afterward, the hepatic juice enters gallbladder for temporary storage. Antioxidants help keep you young.
Also, note that the gall or bile behaves like an anti-oxidant. Therefore, the gall can remove toxins from the blood and ingested food.
On the other hand, playing the role of an anti-oxidant, bile juice counters the poisonous effects of these substances.
Another important thing, worth mentioning here, is that the removal of these free radicals also serves to delay the process of aging. So, you look young when actually you are not! As bile is alkaline in nature, it also helps to neutralize hydrochloric acid in the stomach during times of starvation. Hydrochloric acid or HCL, in the stomach, has a pH value of 2. This strong acidic concentration helps in the digestion of proteins present in the food. First, the inactive pepsinogen converts into an active pepsin enzyme in this acidic medium.
The digestion of fats, on the other hand, requires an alkaline medium. So, bile comes to play its role here. It quickly turns the acidic medium into alkaline one as food enters the small intestine after partial digestion in the stomach. Another significant gallbladder function is that of the emulsification of lipids.
The bile juice, coming from the gallbladder, also has the potential to emulsify lipids or fatty substances in the diet. Thereby, it becomes easier for the enzymes to undergo the digestion of emulsified fats. As an emulsifier of fats, the bile aids a great deal in the process of food digestion. Bile is also important from the point of view of the absorption of food. This fluid assists in the uptake of fats and fat-soluble molecules across the wall of the small intestine into the body.
After entering the bloodstream, these small food particles travel through blood vessels. Finally, these food particles reach every individual cell. The powerhouses of the cells, mitochondria, carry out the further breakdown of these particles. This breakdown occurs through the process of respiration to extract energy present in the bonds of compounds. How does the gallbladder regulate the composition of bile? It is the unique absorptive and secretive capacity of the walls that the bile composition is maintained at the required level.
The epithelium of the gallbladder is specialized to secrete the compounds like bicarbonate and mucins. Both these types of compounds provide cytoprotection, i. The elimination of waste products is another gallbladder function. The gallbladder plays an important role in the disposal of waste products from the body.
The waste substances, including bilirubin, are secreted into the bile. In this capacity, it can be considered an accessory organ of the excretory system. During the recycling of red blood cells by the liver, bilirubin is produced as a by-product.
This gall then empties into the small intestine. From there, it travels along with other waste products in the intestine towards the posterior end of the gastrointestinal canal. The gallbladder diseases are of several different types.
Sometimes, they are infectious in nature and may occur due to the attack of germs, cholelithiasis formation of gallstones , or some other cause. At times, this small organ may also fall victim to some sort of malignancy or a cancerous condition. You can have an idea about the widespread occurrence of gallstones from the fact that as many as , individuals undergo cholecystectomy in the US alone.
And it has become the most frequently performed surgical procedure of the gastrointestinal tract in the country. The gallstones are usually of two types. Based on their composition, they are called cholesterol stones and pigment stones.
The first type, i. As the name suggests, cholesterol stones result from the supersaturation of cholesterol in the bile. Cholesterol is one of the major components of bile along with bile acids and phospholipids. Bile also contains plenty of water, bile salts, bile pigments, triglycerides, and electrolytes. The pigment stones may be composed of either calcium palmitate or calcium bilirubinate.
They may be colored black or brown. The black stones are usually associated with cirrhosis or hemolytic conditions. On the other hand, the brown pigment stones are associated with bacterial infections and the disorders of biliary motility.
Cholecystitis is one of the several complications of cholelithiasis. Other complications include choledocholithiasis common bile duct stone and gallstone ileus reversible reduction in gastrointestinal mobility caused by a gallstone. The condition of cholecystitis refers to the inflammation of the biliary vesicle. There can be different background factors for the onset of this disease, such as gallstones.
The gallstones cause an obstruction in the bile duct which carries gall and empties it into the small intestine. The accumulation of hepatic juice leads to high swelling in the organ. Gallbladder cancer is the development of malignant cells in the organ.
Here it is important to note that the malignancy of biliary vesicle is usually very rare. The diagnosis of the condition is also very difficult. It is because the symptoms of cancer and other diseases are usually very similar and include fever, jaundice, nausea, and vomiting. Especially when you know the role of gallbladder is vital in the digestive system, it is surprising to note that people can survive and lead a normal healthy life even without this organ.
In the case of gallstones, the organ is removed from the body through a surgical procedure. However, this surgical operation is quite expensive. And there are risks associated with such surgeries. Nevertheless, this biliary vesicle has got certain very important roles to play in your body. The gallbladder functions include serving as a storehouse for bile and acting as an antioxidant. The emulsification of lipids, contribution to digestion, facilitation of absorption, and elimination of waste products are also the functions of the gallbladder.
