Which is a effect of superficial heat?

• A. Vasoconstriction
• B. Decreased tissue elasticity
• C. Vasodilation
• D. Reduced blood flow

Answer: (C)

Superficial heat causes dilation of the small arteries in the skin, increasing local blood flow. This vasodilation brings more warm blood to the area, helping dissipate heat and deliver oxygen and nutrients, while also warming the tissues and often increasing tissue elasticity. So the best answer is the one that describes vasodilation. Vasoconstriction would occur with cold, not heat, reduced blood flow contradicts the heat response, and heat actually tends to increase tissue elasticity rather than decrease it.
