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.
