Latest Human gastrointestinal tract Stories
Cedars-Sinai researchers say their examination of the fungi in the intestines suggests an important link between these microbes and inflammatory diseases such as ulcerative colitis.
First-of-its-kind research presented as an abstract at the 2012 American Society for Nutrition suggests eating pistachios may positively impact bacterial profile of the digestive tract
Researchers from the Hotchkiss Brain Institute (HBI) and the Snyder Institute for Chronic Diseases at the University of Calgary's Faculty of Medicine have discovered a pathway that may contribute to the symptoms related to Crohn's disease and ulcerative colitis, collectively known as Inflammatory Bowel Disease (IBD).
Scientists have found that the gut endoderm has a significant role in propagating the information that determines whether organs develop in the stereotypical left-right pattern.
Functional foods containing bacteria with beneficial health effects, or probiotics, have long been consumed in Northern Europe and are becoming increasingly popular elsewhere.
A leaky gut may be the root of some cancers forming in the rest of the body, a new study published online Feb. 21 in PLoS ONE by Thomas Jefferson University researchers suggests.
An interesting observation has been made that many autistic children have a different kind of bacteria in their intestinal tract than non-autistic children do.
The Biology Website EurekaMag.com publishes insights into all areas of biological and health science.
The underlying reason autism is often associated with gastrointestinal problems is an unknown, but new results to be published in the online journal mBio® on January 10 reveal that the guts of autistic children differ from other children in at least one important way: many children with autism harbor a type of bacteria in their guts that non-autistic children do not.
Duodenal atresia is a congenital closure of the lumen of the duodenum, which is the first portion of the small intestine and is separated from the stomach by the pyloric sphincter. During fetal development, the duodenum develops from the posterior portion of the foregut and the anterior portion of the midgut. The liver and pancreas originate from the diverticulum arising from the ventral part of the duodenum, and the bile duct runs along the ventral free side of the duodenum. Rotation and...
The large intestine is the organ that follows the small intestine but is the last part of the digestive tract before the waste leaves the body. Formation and Orientation The small intestine is on average about five feet long. It is composed of four distinct structural parts; the cecum, colon, and anus. The cecum is the part of the large intestine that comes first. It is separated into three parts. The taeniae coli are three bands of smooth muscle. The haustra are bulges caused by...
The esophagus is the muscular tube that is located between the pharynx and the stomach that aids in digestion during swallowing. Formation and Orientation The esophagus is composed of four separate layers; the mucosa, submucosa, muscularis externa and the adventitia. The mucosa includes the stratified squamous epithelium, lamina propria and muscularis mucosae. The submucosa houses the esophageal glands and connective papillae. The muscularis externa is composed of three sublayers The...
The gall bladder is the sac-shaped organ that is the passage between the liver and intestine where bile is held. Formation and Orientation The gall bladder is relatively 8 cm by 4 cm when fully formed. The gallbladder is angled between the rectus abdominis muscle and the costal margin. It is hollow and is made up of three parts; the fundus, the body and the neck. The fundus is the part of the gallbladder that is most far from the cystic duct. This is at the same level of the...
The small intestine is the part of the digestive tract that follows the stomach and is followed by the large intestine. Formation and Orientation The small intestine is on average between 22 feet 6 inches and 24 feet 4 inches. It is composed of three distinct structural parts; the duodenum, the jejunum, and the ileum. The duodenum is the part of the intestine where most chemical breakdown happens; it is also the shortest part of the intestine. It starts at the duodenal bulb and stops...
