94
Mouth (Oral Cavity)
Food begins its journey through the digestive system in the mouth. Other organs of the oral cavity also aid in the digestion of food: lips, tongue, palate (roof of the mouth), teeth, and salivary glands. The lips hold the food in the mouth while the teeth chop it into small pieces. The food is moistened by saliva before the tongue pushes it into the throat. The soft palate prevents food and liquid from moving upward into the nasal cavity during swallowing.
95
Pharynx (Throat)
The pharynx allows the chewed food to pass from the mouth to the esophagus. A flap of tissue, known as the epiglottis, closes off the entrance to the trachea (windpipe) during swallowing.
96
Esophagus
The esophagus is a muscular tube that carries food and liquids from the pharynx to the stomach. The esophagus walls propel food to the stomach by rhythmic waves of muscular contractions called peristalsis.
97
Stomach
The stomach is a hollow sac that serves as a storage area for food. It also mixes the food with acid and enzymes, so it is more easily digested. Mucus coats the cells of the stomach lining to protect them from damage by the acid and enzymes.
98
Small Intestine
The stomach releases food into the small intestine. This coiled organ takes up most of the space in the abdominal cavity and consists of three sections: duodenum, jejunum, and ileum. Ultimately, by the time food leaves the small intestines, about 90% of the nutrients have been absorbed into the bloodstream.
99
Large Intestine
The large intestine wraps around the top and sides of the small intestine. Here, the waste products of digestion are processed in preparation for excretion from the body. The many bacteria that inhabit the large intestine can further digest some material. The major parts of the large intestine are the cecum, colon, rectum, and anus.
100
Liver
The liver is the largest internal organ in the body. The liver has many different functions, but its primary function in digestion is to produce bile and secrete it into the small intestine. Bile is a greenish-yellow fluid that is necessary for the digestion of fat.
101
Gallbladder
The gallbladder stores bile for later use.
102
Pancreas
The pancreas is a glandular organ in the upper abdomen. It secretes pancreatic juices (water, salt, sodium bicarbonate, and digestive enzymes) to aid in digestion and help neutralize stomach acids.
103
Gastroesophageal Reflux Disease (GERD)
a condition described by the backward flow of stomach acid into the esophagus. At the lower end of the esophagus, where it joins the stomach, is a circular ring of muscle called the lower esophageal sphincter. After swallowing, the sphincter relaxes to allow food to enter the stomach and then contracts to prevent the backup of food and acid into the esophagus. Acid reflux happens when this sphincter doesn't tighten or close properly, allowing digestive juices and other contents from the stomach to rise up into the esophagus.
104
Hiatal Hernia
occurs when a portion of the stomach protrudes upward, through the diaphragm, and into the chest. This is usually due to an anatomical abnormality. The word hiatal comes from the root hiat/o, meaning opening, and the suffix -al, meaning pertaining to. A hiatal hernia may be the cause of GERD.
105
Gastric Inflammation
an inflammation of the mucous membrane that lines the stomach and intestines
106
Peptic Ulcers
sores within the lining of the mucous membrane of the digestive system. Helicobacter pylori infections often cause peptic ulcers. Peptic ulcers may occur in the stomach, called gastric ulcers. They may occur in the upper part of the small intestine, called duodenal ulcers. If a peptic ulcer erodes through the entire thickness of the organ wall, it is called a perforated ulcer.
107
Ulcerative Colitis (UC)
an inflammatory bowel disease. With UC, the person's immune system identifies the lining of the colon as foreign and attacks it, leading to inflammation. This inflammation causes the lining to develop ulcers and bleed. The cause is unknown, and the condition cannot be cured. However, it can usually be controlled with medication. For most people, ulcerative colitis has a frustrating pattern of flares (condition worsens) and remissions (symptoms are absent).
108
Crohn's Disease
an inflammatory bowel disease. Like ulcerative colitis, the body's immune system identifies the lining of the digestive tract as foreign and attacks it, causing inflammation. The disease also follows a repeating cycle of intermittent flares and periods of remission. There is no cure for Crohn's disease, but medicines can help to keep the disease under control. If medicine does not control symptoms, surgery might be an option to remove the diseased part of the intestines.
109
Diverticulosis
Diverticula are small, bulging pouches that are most commonly located in the colon. A single pouch is called a diverticulum. These pouches occur when the inner layer of the digestive tract pushes through weak spots in the outer layer. Most people with this condition, called diverticulosis, are unaware because it usually does not cause symptoms. Most doctors believe this condition is due to a diet low in fiber. A low-fiber diet leads to constipation, which increases pressure within the digestive tract with straining during bowel movements. The combination of pressure and straining over many years likely leads to the development of diverticula.
110
Diverticulitis
Diverticulosis may lead to diverticulitis, which occurs when bacteria are trapped in the diverticula, infecting them. This condition usually produces localized abdominal pain, nausea, vomiting, constipation, and fever. Treatment includes antibiotics to treat the infection and a liquid diet to allow the bowel to heal. Repeated attacks of diverticulitis may require surgery to remove the affected portion of the colon.
111
Cholangiography
uses contrast medium to take radiographs of the bile ducts. It is used to determine if there are obstructions in the ducts that may slow or block the flow of bile.
112
Esophagogastroduodenoscopy
the use of an endoscope to visualize the upper GI tract.
113
Palatoplasty
the surgical repair of a cleft palate or cleft lip.
114
Gastroduodenostomy
a surgical procedure to create an anastomosis between the upper part of the stomach and the duodenum
115
Anastomosis
a surgical connection between two hollow structures
