Carbon dioxide is a by-product of respiration.] . This increase in respiration generates more waste heat to warm the body back up. Vasoconstriction occurs â the muscles in the wall of the blood vessels supplying the skin capillaries contract causing the blood vessel to constrict [constrict: To get narrow.] . This reduces the flow of blood into the capillaries and allows less blood to flow near the surface of the skin.
Vasodilation occurs â the muscles in the wall of the blood vessels supplying the skin capillaries relax causing the blood vessel to dilate. This increases the flow of blood into the capillaries and allows more blood to flow near the surface of the skin.ote that the capillaries themselves do not constrict/dilate â it is the blood vessels supplying the capillaries that do this. Nor do the blood vessels move closer to/further from the skin surface. These are two common mistakes made in exams.
