Body the part of the gallbladder between the funds and the neck, is called the body.

The body lies in contact and the undersurface of the liver. Neck: The neck is the part of the gallbladder that lies closest to the cystic duct, and it connects the body of the gallbladder to the cystic duct. The body and neck of the gallbladder is 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, which carries bile to the small intestines. The sphincter of Odd 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 intestines, it Soma Biotics stimulates the release of a hormone cholecystitis 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 Odd, 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 duct, causing a blockage. This condition is more common in people 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 symptoms, 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 break the stones into smaller fragments, is also used. The surgical treatment involves removal of the gallbladder by a process termed as cholecystectomy. After the surgery, provision is made for the bile to pass through the ducts directly from the liver to the small intestine. 

The surgery is simple 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 and medications after consulting a doctor. Digestion is the process of breaking down food into smaller molecules that can be easily absorbed by the body to use as energy to build and nourish cells. The human digestive system provides the body and all the necessary carbohydrates, vitamins, fats and amino acids, that keep the estimated 50-75 trillion cells, functioning. It also eliminates all the waste products from the body. Throughout this process, there are many organs that contribute to the breaking down of food. Here are all the organs that are involved in the process, along and their functions. You can also refer to the diagram below to know the exact position of the organs. The Different Organs of the Digestive System and their Functions the human digestive system can be classified into two basic sections, the upper gastrointestinal tract and the lower gastrointestinal tract. Upper Gastrointestinal Tract The process of digestion starts in the upper gastrointestinal tract which comprises the mouth, teeth, tongue, pharynx, esophagus and the stomach. Mouth: This is the first organ that begins the digestion process and it is here that mastication or breaking down of food takes place. 

The mouth further contains three basic organs - the salivary glands, tongue and the teeth. Salivary glands: When the mouth receives food, three pairs of exocrine salivary glands secrete saliva, which acts as a lubricating agent to moisten food. Saliva also produces a called amylase that breaks down the starch present in highly starchy food into sugar or maltose. The saliva also contains some disinfecting or antibacterial properties which kills some of the bacteria and fungi during the chewing process. Tongue: This primary organ of taste has much more to it than just taste buds. It helps in the chewing and swallowing process which is also known as deglutition. The tongue guides the food and keeps it between the upper and lower teeth. The masticated food, called bolus is then swallowed. Teeth Just like the tongue, the human teeth play an important role in preparing the food for digestion. As the tongue pushes the food against the teeth, it starts chewing and breaking it into smaller pieces. Though, the teeth do not play an active role in the chemical simplification of the food, chewing makes it easier for other organs to break down food and absorb nutrients. Pharynx The pharynx or throat lies behind the mouth or the buckle cavity. The main role of the pharynx is to prevent the food from entering the voice box or larynx and divert it to the esophagus. Esophagus The esophagus is a muscular tube that connects the mouth to the stomach. It is around 10 inches long and about 1-inch wide. 

Once the food is masticated, it passes through the esophagus which has two sphincters that remain closed except during swallowing. Though, the pharynx and esophagus are not directly related to the actual simplification of food, their function of conveyance of food is extremely important for the gastrointestinal tract. Stomach The stomach is the organ that conducts the mammoth task of breaking down food. It receives the ingested food from the esophagus and mixes it and gastric juices to further break it down. The stomach is divided into four parts. The cardiac receives the bolus from the esophagus. It then goes through the funds, which is the uppermost part of the stomach. The stomach can dilate to accommodate about a quarter of food and liquid and out putting pressure on the stomach. Then the bolus is transported to the largest part of the stomach, the corpus or simply the body and it is here that the bolus is converted into chime. Chime is the semi-fluid partially digested food that is mixed and gastric juices. The chime now goes through the tantrum, which is the lowest part of the stomach. It is funnel-shaped and joins the stomach and the duodenum. Lower Gastrointestinal Tract The lower gastrointestinal tract comprises the small intestine, large intestine and the anus. During digestion the lower gastrointestinal tract helps the body to assimilate all the nutrients that have been simplified by the upper gastrointestinal tract. Small intestine: Also known as the small bowel, the small intestine is the longest section of the digestive tract. 

However, it is called the small intestine because it has a smaller diameter than the large intestine. The main purpose of the small intestine is to absorb nutrients from the food during digestion. It is made up of three parts - the duodenum, jejunum and the ileum. Duodenum: The duodenum is the shortest part of the small intestine and is connected to the lower portion of the stomach. The main function of the duodenum is to break down the food using secreted by the pancreas and bile secreted by the liver. The jejunum is the mid-section of the small intestine. The most important function of this organ is the absorption of carbohydrates and proteins. It has a specialized lining and small, finger-like projections called villa. This villa increases the internal absorptive surface area which in turn helps in the absorption of more nutrients. The villa is also connected to the blood vessels so that the circulating blood can carry the nutrients to different parts of the body. Ileum: The ileum is the final section of the small intestine.
