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.
As a consequence, the blood pressure usually increases by 20 to 60 mm Hg, which helps sustain the increased blood flow through skeletal muscle blood vessels. In response to sympathetic stimulation, some decrease in the blood flow through the skin can occur at the beginning of exercise. However, as the body temperature increases in response to the increased muscular activity, temperature receptors in the hypothalamus are stimulated. As a result, action potentials in sympathetic nerve fibers causing vasoconstriction decrease, resulting in vasodilation of blood vessels in the skin.
