The DUODENUM is part of the hollow organs that make up the GI tract, particularly in the small intestine. The lining of the duodenum has hormone glands that send signals to the liver, gallbladder, and pancreas to release their chemicals when food is present. Moreover, duodenum consists of the four layers characteristic of the gastrointestinal tract: mucosa, submucosa, muscularis externa, and adventitia.
The ILEUM is where segmentation slows down and peristalsis takes over, moving food waste gradually toward the large intestine. There is an ileocecal valve in it that separates the ileum from the large intestine. Moreover, this is the last location of nutrient absorption and it is composed of the four layers characteristic of the gastrointestinal tract: mucosa, submucosa, muscularis externa, and adventitia.
The ESOPHAGUS is also part of the hollow organs of the GIT. It carries food and liquid from your mouth to your stomach. The esophagus is a muscular tube composed of the four layers characteristic of the gastrointestinal tract: mucosa, submucosa, muscularis externa, and adventitia.
