Prostoglandins are found in cell membranes, they are released due to injury. They cause the dilation of small arteries and arterioles and increase the permeability of the capillaries. They affect neurotransmitters and blood pressure and hence pain sensation.

What is vaso-dilation and vaso-constriction in terms of control of internal body temperature?
If our body overheats, capillaries beneath the surface of the skin widen to allow more blood to flow through them. The blood carries heat energy, which can then leave the body when we sweat. Hence we cool down. If we are too cold, the capillaries narrow to reduce the volume of blood passing through. This reduces the amount of heat that is lost, and so we don't freeze to death as easily.
