Answer:
corrugated cardboard tube - digestive tract
irregular surfaces on the corrugated tube - villi
pump - heart
Plastic tubing - blood vessels
Explanation:
The corrugated cardboard tube represents the digestive tract. The give away was the presence of the irregular surfaces within the tubes. This is called the villi. The villi is responsible for the absorption of food after digestion into the body.
Irregular surfaces on the corrugated tube represent the villi. They are tiny hair-like structures that are in the small intestine, that are responsible for the absorption of food into the bloodstream.
The pump represents the heart. The heart is the only organ in the body that provides the pressure force that pushes the blood throughout the body. In this model, the pump will most likely be performing the same function.
The plastic tubings are meant to contain one form of fluid or the other. Judging from that, they can be said to represent the blood vessels. This is because they are connected to the heart and are meant to transport bodily fluids around the body

The correct answer is "<span>the blood vessels of the dermis have undergone vasodilation, bringing a greater volume of blood to the skin"
This is because heat signals the temperature regulating center of the hypothalamus then the hypothalamus will respond to that signal by activating the sympathetic nervous system causing the vasodilation of the cutaneous blood vessels leading to more blood flow essentially cooling the skin by letting more heat to the outside environment.</span>
