Which term means redness of the skin due to capillary dilation?

• A. Erythrocytes
• B. Erythema
• C. Hemorrhoids
• D. Endocarditis

Answer: (B)

Redness of the skin from capillary dilation happens when tiny blood vessels widen, allowing more blood to flow near the surface and giving the skin a red appearance. This visible change is described by the term erythema. Erythrocytes are red blood cells that carry oxygen, but they’re not a description of the skin’s redness. Hemorrhoids are swollen veins in the rectal area, not a general skin redness. Endocarditis is an infection of the heart’s inner lining, unrelated to skin coloration. So the best term for redness caused by capillary dilation is erythema.
