Which term refers to 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 is described as erythema. When tissues become irritated or inflamed, the tiny vessels near the surface widen, increasing blood flow to the area and giving the skin a red appearance. The term erythema comes from roots meaning “red” and “condition,” so it specifically denotes redness. This is different from erythrocytes, which are the red blood cells circulating in the blood; hemorrhoids, which are swollen veins in the rectum; and endocarditis, which is inflammation of the heart’s inner lining.
