the large gland in the upper right part of the abdomen. In addition to many other functions, it secretes bile needed for digestion and absorption of fats (root: hepat/o)
51
lower esophageal sphincter (LES)
muscle tissue at the distal end of the esophagus (gastroesophageal junction) that prevents stomach contents from refluxing into the esophagus. Also called the cardiac sphincter
52
mastication
chewing
53
mouth
the oral cavity; contains the tongue and teeth. Used to take in and chew food, mix it with saliva, and move it toward the throat to be swallowed
54
palate
the roof of the mouth; the partition between the mouth and nasal cavity; consists of an anterior portion formed by bone, the hard palate, and a posterior portion formed of tissue, the soft palate (root: palat/o)
55
pancreas
a large, elongated gland behind the stomach. It produces hormones that regulate sugar metabolism and also produces digestive enzymes (root: pancreat/o)
56
peristalsis
wave-like contractions of an organ's walls; moves material through an organ or duct
57
peritoneum
the serous membrane that lines the abdominal cavity and supports the abdominal organs
58
pharynx
the throat; a common passageway for food entering the esophagus and air entering the larynx (root: pharyng/o)
59
pylorus
the stomach's distal opening into the duodenum. The opening is controlled by a ring of muscle, the pyloric sphincter (root: pylor/o)
60
rectum
the distal portion of the large intestine. It stores and eliminates undigested waste (root: rect/o, proct/o)
61
saliva
the clear secretion released into the mouth that moistens food and contains a starch-digesting enzyme (root: sial/o). Saliva is produced by three pairs of glands: the parotid, submandibular, and sublingual glands
62
sigmoid colon
distal S-shaped portion of the large intestine located between the descending colon and the rectum
63
small intestine
the portion of the intestine between the stomach and the large intestine; comprised of the duodenum, jejunum, and ileum. Accessory organs secrete into the small intestine, and almost all digestion and absorption occur there
64
stomach
a muscular sac-like organ below the diaphragm that stores food and secretes juices that digest proteins (root: gastr/o)
65
uvula
the fleshy mass that hangs from the soft palate; aids in speech production (literally “little grape”) (root: uvul/o)
66
villi
tiny projections in the lining of the small intestine that absorb digested foods into the circulation (singular: villus)
67
appendicitis
inflammation of the appendix
68
ascites
accumulation of fluid in the abdominal cavity; a form of edema. May be caused by heart disease, lymphatic or venous obstruction, cirrhosis, or changes in plasma composition
69
bilirubin
a pigment released in the breakdown of hemoglobin from red blood cells; mainly excreted by the liver in bile
70
caries
tooth decay
71
celiac disease
inability to absorb foods containing gluten, a protein found in wheat and some other grains; caused by an excess immune response to gluten
72
cholecystitis
inflammation of the gallbladder
73
cholelithiasis
the condition of having stones in the gallbladder; also used to refer to stones in the common bile duct
74
cirrhosis
chronic liver disease with degeneration of liver tissue
75
Crohn disease
a chronic inflammatory disease of the gastrointestinal tract usually involving the ileum and colon
76
diarrhea
the frequent passage of watery bowel movements
77
diverticulitis
inflammation of diverticula (small pouches) in the wall of the digestive tract, especially in the colon

condition caused by reflux of gastric juices into the esophagus resulting in heartburn, regurgitation, inflammation, and possible damage to the esophagus; caused by weakness of the lower esophageal sphincter (LES)
