When a human being is cold, the superficial blood vessels

• A. Dilate, and the sweat glands are inactive
• B. Dilate, and the sweat glands are active
• C. Constrict, and the sweat glands are inactive
• D. Constrict, and the sweat glands are active

Answer 1

The correct option is C Constrict, and the sweat glands are inactive

Vasoconstriction occurs in superficial blood vessels of warm-blood vessels of warm-blooded animals when their ambient environment is cold, this process diverts the flow of heated blood to the center of the animal, preventing the loss of heat

So, the correct answer is 'constricted, and the sweat glands are inactive'
