ERCP is a combination of two tests: an endoscopy and an X-ray. An endoscopy is a procedure in which a thin, flexible tube attached to a tiny camera is threaded down to your gastrointestinal (GI) tract. Your GI tract consists of your esophagus, stomach, and intestines.
HOMOGRAPHS are words that are spelled the same but have different meanings. Heteronyms are a type of homograph that are also spelled the same and have different meanings, but sound different. WORDS THAT BOTH SOUND THE SAME AND ARE SPELLED THE SAME are both homonyms (same sound) and homographs (same spelling). Example: lie (untruth) and lie (prone); fair (county fair), fair (reasonable).
A homophone is a word that is pronounced the same as another word but differs in meaning, and may differ in spelling. The words may be spelled the same, such as rose (flower) and rose (past tense of rise), or differently, such as carat, caret, and carrot, or to, two, and too.
