The human digestive tract is approximately 7 to 7.9 m (23 to 26 feet) long.

A hollow muscular tube that connects the mouth to the stomach.

The stomach is located in the left upper portion of the abdomen under the left lobe of the liver.

The stomach can hold approximately 1500 mL of food and liquids.

The region controlling the opening between the stomach and small intestine.

The stomach has four regions: Cardia, Fundus, Body, and Pylorus.

The longest segment of the GI tract, about 70 m (230 feet) long, where absorption occurs.

The stomach stores food, secretes digestive fluids, and propels chyme into the small intestine.

A circular smooth muscle that controls the exit of chyme from the stomach to the small intestine.

The first section of the small intestine, where initial digestion occurs.

The middle section of the small intestine, involved in nutrient absorption.

The esophagus passes through the diaphragm at the esophageal hiatus.

The final section of the small intestine, leading to the cecum.

The valve where the ileum terminates at the cecum, controlling flow to the large intestine.

Also known as the vermiform appendix, it is an appendage attached to the cecum with unclear function.

The duct that empties bile and pancreatic secretions into the duodenum.

Study of the entire small intestine with radiopaque liquid infusion.

A substance (like barium sulfate) used to enhance imaging contrast in studies.

Patient must follow a low residue diet and be NPO before the study.

Visualizes lower gastrointestinal tract after barium rectal installation.

A procedure to detect polyps, tumors, and abnormalities in the large intestine.

Includes low residue diet and cleansing of lower bowel beforehand.

Imaging technique that provides cross-sectional images of abdominal organs.

Imaging used for evaluating soft tissues, blood vessels, and abnormalities.

Includes abdominal pain, dyspepsia, gas, nausea, diarrhea, constipation, fecal incontinence, and jaundice.

A frequent issue in general practice characterized by pain in the stomach area.

Upper abdominal discomfort associated with eating, commonly known as indigestion.

Excess gas in the GI tract leading to belching and flatulence.

An uncomfortable sensation of sickness or queasiness.

Forceful emptying of the stomach contents through the mouth.

Acute upper GI bleeding indicated by bright red or coffee ground emesis.

Vomiting blood, a sign of upper gastrointestinal bleeding.

Vomiting that contains bile, often greenish in color.

Inability to control bowel movements, resulting in unexpected stool leakage.

An imaging test showing the metabolic activity of tissues using a radioactive tracer.

An imaging technique using radioactive isotopes to assess anatomical structures and lesions.

An endoscopic procedure to examine the upper gastrointestinal tract.

An endoscopic procedure to inspect the colon and rectum for abnormalities.

Tests to evaluate gastric emptying and colonic transit times.

A type of endoscopy that examines the small intestine.

Using an endoscope to examine the digestive tract via an ostomy opening.

Endoscopic examination of the stomach and upper GI tract.

Examination of the anal canal using an endoscope.

Examination of the rectum using an endoscope.

Patients should not eat or drink 8 hours prior to upper GI endoscopy.

A sedative used for moderate sedation during endoscopic procedures.

Medication to reduce secretions prior to GI endoscopy.
