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.
Venules take blood from the capillaries to the veins. Veins take blood back to the heart. This constant circulation of blood keeps us alive. Your blood vessels also play a part in the regulation of your blood pressure. Certain chemicals in the body can cause our blood vessels either to contract or dilate.Signals from our nervous system can also make our blood vessels relax or contract. These changes cause a change in the size of the lumen of the vessel.he heart is a muscular pump that pushes blood through blood vessels around the body. Essential to life, the heart beats continuously, pumping the equivalent of more than 14,000 litres of blood every day. Blood vessels form the living system of tubes that carry blood both to and from the heart.
