Describe the series of events involved in the non-specific response

Damaged cells send out chemicals causing neutrophils to accumulate at the site in the capillary mast cells in the tissue fluid are at the site mast cell release histamines histamines cause vasodilation of local arterioles causing local redness and heat they also make the capillary walls leaky because the endothelial cells part slightly this allows plasma, antibodies and neutrophils to enter and destroy the bacteria this will increase tissue fluid in the capillary causing oedema (swelling)
