Basic components of the immune system part 73

The control of the complement activation is important since many of its components induce inflammation. This control is executed in the following ways.  First,  many of the activated components are unstable and will decay rapidly if the next sequence is not present. Second, there are specific inhibitors of each component, such as C1 esterase, which inhibits factors I and H. Finally, the cells themselves contain proteins that increase the rates of breakdown of these products.
