Hemorrhoids Explained: Internal vs. External Anatomy Diagram #133308 (License: Personal Use)

The image is a cross-sectional medical illustration of the anal canal, highlighting two types of hemorrhoids: a larger internal hemorrhoid located above the dentate line within the rectal mucosa, and a smaller external hemorrhoid protruding below the dentate line in the perianal skin. Blue dots represent blood vessels, and surrounding tissues-including the anal sphincter and mucosal folds-are rendered in realistic pink and yellow tones to aid clinical understanding.

Used on health education pages, gastroenterology or proctology websites, and patient-facing medical resources to explain hemorrhoid anatomy, differentiate types, and support diagnosis/treatment discussions. Matches user intent for understanding symptoms, causes, or surgical options.
