Which of the following is NOT a mechanism used by the immune system to fight multicellular parasites? Select one: a. Antibodies coating the pathogen surface bind to FcRs on mast cells, causing release of granule contents onto surface, and damage the parasite. b. Crosslinking of antibody binding to FceRI on eosinophils cells triggers release of granules, causing smooth muscle contractions. Muscle contractions in the mucosal tracts causes sneezing, coughing, vomiting or diarrhea, dislodging the parasite. d. The parasite is killed and broken down extracellularly, and then phagocytosed by macrophages. C.

Immunology

Immunology is the division of science involved with the immune reactions occurring in living organisms. The organisms are accustomed to evolving internal defense mechanisms to evade the invasion of microbial pathogens. Diverse cells are connected with stimulating the immune responses, which produce inhospitable conditions to the microbes prompting their lysis and thus inhibits the multiplication of the pathogens. The immune system can distinguish the pathogens through the aid of cellular intercommunication and launch responses to destroy them.
