The primary actions of the complement cascade include:
A) increased vascular permeability and vasodilation, chemotaxis, opsonization, and cell killing.
B) mast cell degranulation, activation of T cells, formation of immunoglobulins, and angiogenesis.

D) release of pyrogens, prostaglandins, and stimulation of fibroblasts.

Question

Quizplus · Accepted Answer

The primary actions of the complement cascade include increased vascular permeability and vasodilation (which promote the recruitment of immune cells), chemotaxis (to direct immune cells to the site of infection/inflammation), opsonization (to enhance phagocytosis of pathogens by immune cells), and cell killing (by forming membrane attack complexes that cause lysis of pathogens).
