the liver to be cleared? correct answers haptoglobin
What is the name of the process by which phagocytic cells are attracted toward a substance such
as a bacterial peptide? correct answers chemotaxis

following correct answers osmotic cytolysis
What is the purpose of C3a, C4a, and C5a, the split products of the complement cascade? correct
answers to cause increased vascular permeability, contraction of smooth muscle, and release of
histamine from basophils
Which of the following complement components is found in both the classic and alternative
pathways? correct answers C3
