The term for redness caused by vasodilation is which of the following?

• A. Erythema
• B. Pale
• C. Flushed
• D. Cyanotic

Answer: (C)

When blood vessels in the skin widen (vasodilation), more blood flows to the surface, giving the skin a red, warm appearance. This visible change is described as flushing. Erythema is a general term for redness, but flushing specifically denotes the reddened look caused by vasodilation, often seen on the face. Pale results from reduced blood flow (vasoconstriction), and cyanotic is a blue discoloration from deoxygenated blood, so they don’t describe the red, dilated-skin state.
