one of the mechanical or physical consequences of these chemical signals like Incan 1 Incan 6 tnf Alpha again those are all cyto kindes being drawn to a particular cell or region of cells that have been infected is that it creates some physical swelling of the area it impacts the vasculature the veins and capillaries that feed that area and in response to they put more blood there so you get some swelling or you'll get in some cases the release of histamines right we think of anti-histamine drugs well histamines are an aspect of your immune system they move around in your body in these really cool cells called masted cells Mas mass cells and when the histamines are released that area becomes kind of hot and swelling it's what we call edema and that whole area is marked as really a sight just like a crash site on the side of the road it's like hey we've got eat me signals to get the debris and the bad stuff out of here try to get those viruses out of here we've got help me signals to try and help the injured cells just like you would try and help people at a car crash and there's a bunch of swelling so there's additional blood flow sometimes there's some other physical features as well
