Duodenum

It is shorter because they only focus on absorptions. Small intestine are divided into duodenum, jejunum, and ileum. It have kerckring folds to slow down passage of ingested food. Circular folds increase surface area. Which lead to increase in number of villus and enterocytes in . Allowing increase in absorption. In the small intestine, there…

Pseudomelanosis gastri and duodeni is a rare endoscopic mucosal finding, characterized by the accumulation of iron in macrophages of the lamina propria of the stomach and duodenum. The clinical significance and long term sequelae have not been clarified. However, this benign condition is associated with a variety of clinical conditions, such as essential hypertension, chronic renal failure, diabetes mellitus, long term intake of iron supplements and furosemide. Pseudomelanosis duodeni appears to…

cardiac sphincter that controls the entrance of food into the stomach from the esophagus. The top portion of the stomach is called the fundus with the lower portion called the body. The pyloric section is the most posterior that ends with joining the duodenum. Here there is the pyloric sphincter which regulates the release of partially digested food into the…

they are combined with proteins to creat lipoproteins which are then used to transport cholesterol in the blood and are absorbed into lymph. Dietary vitamins, pentose, sugars, phosphate ions, iron, calcium, and most electrolytes are absorbed in the duodenum and transported across the epithelium and enter the blood.The journey of food through the small intestine takes three to six hours. Most of the water from chyme is absorbed via osmosis while in the small intestine as well as nutrients thus…

called Chyme. This acidic, Chyme reaches the lower GI tract through the pyloric sphincter of the stomach. Chyme passes through the pyloric sphincter and enters the duodenum. The duodenum is apart of the small intestine and is located inferior to the right of the stomach. Absorptions of nutrients also takes place in the walls of the duodenum. The jejunum is located in the middle part of the small intestine and is also located…

Normally it has an average weight of 90 g, and is shaped like a tadpole, that is divided into four main anatomical areas: head, neck, body, and tail (7). The pancreatic head is the thickest portion of the pancreas and lies within the C-loop of the duodenum, to the right of the superior mesenteric and portal veins. The neck of the pancreas is the narrowest portion of the gland with a width less than 2 cm; lengthwise it traverses the mesenteric blood vessels anteriorly, connecting the pancreatic…

The exocrine function is the releasing of enzymes by the pancreas into the duodenum, the first 25cm of the small intestine, joining with the bile that is produced in the liver and stored in the gallbladder. The pancreas produces pancreatic juice and sodium bicarbonate, NaHCO3. Pancreatic juice contains three hydrolytic enzymes:…

Tongue: The tongue is a large muscle found inside of the pigs mouth. It has a rough light colored surface that has taste buds and saliva on it. It function is to help the pig with swallowing its food by pushing it to the back of the pig’s mouth and down the esophagus. The tongue is a part of the digestive system because it aids in the digestion of food. Saliva: The saliva is found all throughout the pigs digestive system but mainly in the mouth. It is a clear liquid that functions as a…

2009). When food is consumed and enters the small intestine, cholecystokinin is released which triggers the gallbladder to contract and secrete bile. The gallbladder is not essential for survival however, as the liver will instead drip bile into the duodenum during this process instead if the gallbladder is absent (Ellis,…

The mouth is the beginning of the digestive track, Chewing breaks the food down into small pieces so you can easily digest them. The saliva mixes the food to begin the process of breaking it down into a form to which your body can use. Once you swallow the food then travels to your Throat (Pharynx), from the throat your food then goes through your esophagus or swallowing tube. The esophagus is a muscular tube leading from the throat to the stomach. While in the esophagus the food goes through a…
