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.
If the body is too hot... ...the blood vessels leading to the skin capillaries dilate, known as vasodilation. This allows lots of blood to flow near the surface and heat is lost through the skin by convection and radiation.The hairs of the body lie flat to avoid trapping an insulating layer of air.hanges in core body temperature cause the hypothalamus to send nerve impulses to the sweat glands, muscles and blood vessels to raise or lower the temperature. If the core temperature goes up the body loses heat to bring it down again.
