which immune system component initially results in the inflammation and responds quickly when staphylococcus aureus enters the bloodstream?\ncomplement system\nphagocytes\nlangerhans cells\nb lymphocytes
Answer
Brief Explanations:
The complement system is part of the innate immune response and can quickly trigger inflammation when pathogens like Staphylococcus aureus enter the bloodstream. Phagocytes are involved in engulfing pathogens but not the initial inflammation - trigger in this context. Langerhans cells are mainly in the skin and mucosa for antigen - presentation. B lymphocytes are part of the adaptive immune response and not the immediate responder for inflammation upon pathogen entry into the bloodstream.
Answer:
complement system
