What is the complement system and how does it function?
What will be an ideal response?
The complement system is a group of about 20 proteins that circulate in the plasma and can attack and destroy bacteria, and also stimulate inflammation (the swelling, redness, and heat experienced during an infection). When these proteins are activated by either antibody binding or molecules in the cell wall of the bacteria, they intensify other specific and non-specific modes of resistance, hence the name (complement).
