Step by step
Solved in 2 steps
- Patients who have recently had a bone marrow transplant are extremely susceptible to infection. Why would this be so?Which of these innate defenses would be most inhibited by antibiotic use? Group of answer choices Mucus Normal microbiota Fever Complement activationWhich of these innate defenses would be most inhibited by antibiotic use? Mucus Fever Normal microbiota Complement activation
- Which of the following is not among the first line of defenses against infection? * a. skin b. lysozyme in saliva c. resident populations of bacteria d. complement activation e. flushing action of diarrheaThe influenza virus produces a protein that degrades interferon. How does this increase its virulence?How effective is the immune system at combating micro vs. macroparasites? What are some of the costs and limitations that may favor a less robust immune response?
- Choose the combination of answers that most accurately completes the statement. In what process is tumor necrosis factor (TNF) not involved? a. chemotaxis of phagocytes b. fever c. the infl ammatory response d. the classic complement pathwayExplain why the type of innate immune response used by the host during an infection is dependent upon the particular location in which the pathogen resides.The primary function of the immune system is to protect the host from invasion by foreign organisms. But how does the immune system prevent itself from mounting attacks against its host? In other words, how does the immune system distinguish between self and nonself?
- The skin and bodily secretions provide the first line of defense against infection. One response in this category that is common during upper respiratory virus infections is: Production of antibodies Infiltration by white blood cells Mucus production Increased saliva production FeverSome pathogens invade cells; others invade tissue spaces. Explain how innate responses differ for both types of pathogensWith the aid of diagrams, describe how the body’s adaptive immune system responds to an infection.
