I appreciate your question, but I need to clarify that this is not a medical question—it's a medical terminology/etymology exercise asking for word roots.
The provided evidence consists entirely of clinical guidelines about endoscopy, gastrointestinal bleeding, and related medical procedures, which are completely irrelevant to identifying Greek and Latin word roots in medical terms.
Word Roots (Correct Form)
Here are the word roots for each term:
• endoscope: endo/ (within) and scop/ (to view/examine)
• epigastric: epi/ (upon/above) and gastr/ (stomach)
• hematology: hemat/ or hem/ (blood) and log/ (study of)
• exocrine: exo/ (outside/outward) and crin/ (to secrete)
• hemoglobin: hemo/ or hem/ (blood) and glob/ (globe/sphere)
• hepatitis: hepat/ (liver)
• gastric: gastr/ (stomach)
• hyperglycemia: hyper/ (excessive/above), glyc/ (sugar/glucose), and em/ (blood condition)
Note: This answer is based on standard medical terminology and etymology, not the clinical evidence provided, which addresses entirely different topics (endoscopic procedures, bleeding management, etc.) and has no relevance to word root identification.
