Answer:
Blood vessel dilation in the dermis is allowing increased blood flow from the deeper tissues to the skin.
Explanation:
Our skin feels hot when you have a fever because of the process known as vasodilation in which the widening of blood vessels occurs that increases the blood flow. Due to this process, blood flow to the skin increases that causes the temperature to rise and as as result sweating as well as dehydration occurs in order to remove heat from the body. So we can say that vasodilation is responsible for the increase in temperature of our body.
