or/o
upper gastrointestinal tract
roots
Def: mouth
Ex: oral

roots
Def: mouth
Ex: stomatosis
gingiv/o
upper gastrointestinal tract
roots
Def: gums
Ex: gingivitis, gingivostomatitis

dent/o
upper gastrointestinal tract
roots
Def: tooth
Ex: dentist
Notes: The enamel on the outside of the tooth is the hardest thing in the human body. Adult humans have 32 teeth (or they’re supposed to anyway). An opossum has 50 teeth, a mosquito has 47 teeth, and sharks have as many as 40 sets of teeth in their lifetime.
odont/o

roots
Def: tooth
Ex: odontalgia
gloss/o
upper gastrointestinal tract
roots
Def: tongue
Ex: glossopathy, hypoglossal
Notes: The strongest muscle in the human body, relative to its size, is the tongue. It is also the only muscle in the human body that is attached to only one end. Here’s an interesting fact: Whether or not you can roll your tongue into a tube or other shapes is predetermined by your genetics.
lingu/o
upper gastrointestinal tract
roots
Def: tongue
Ex: sublingual
gastr/o
upper gastrointestinal tract
roots
Def: stomach

upper gastrointestinal tract
roots
Def: esophagus
Ex: esophageal, esophagitis
Notes: The esophagus is a tube that is about the diameter of a quarter; it connects your mouth to your stomach. the name breaks down into eso (carry) and phagus (eat) and literally means “the thing that carries what you eat,” presumably to the stomach.
enter/o
lower gastrointestinal tract
roots
Def: intestines
Ex: gastroenterology, dysentery

lower gastrointestinal tract
roots
Def: duodenum
Ex: gastroduodenoscope, duodenectomy
Notes: The small intestine is divided into three sections: the duodenum, jejunum, and ileum. The duodenum is the first of the three sections. Its name means “twelve” and refers to the fact that its length is about the same as the width of 12 fingers.
jenun/o
lower gastrointestinal tract
roots
Def: jejunum
Ex: jejunotomy, jejunitis

col/o

roots
Def: colon (large intestine)
Ex: colorectal carcinoma, colitis

lower gastrointestinal tract
roots

rect/o
lower gastrointestinal tract
roots
Def: rectum
Ex: rectoplasty, rectitis
Notes: Rectumis Latin for “straight” and refers to the final portion of the colon before it arrives at the anus.
