And what an anaphyllotoxin does is it goes on and bind onto the membrane of either mass cells or onto basin. And it basically stimulates those two types of cells to release a chemical immune chemical known as histamine. So recall that histamine dilates the blood vessels leading to that infection and it also makes the capillaries much more permeable to fluid. And what that means is the blood flow will increase to that infected area. And so the immune cells and immune chemicals will be able to get to that infected area much more quickly. So C three A basically increases the rate at which we can protect our body from these different types of pathogenic infections.
