- Match the immune cell with its main function. ___dendritic cell a. professional phagocyte ___B cell b. antigen-presenter ___helper T cell c. activates other lymphocytes ___NK cell d. makes antibodies ___macrophage e. kills ailing body cells that lack MHC markersWhich of the following is not important in the antiviral innate immune response?a. interferonsb. natural killer cellsc. complementd. microphagesWhich of the following cells would be most active in early, antiviral immune responses the first time one is exposed to pathogen?a. macrophageb. T cellc. neutrophild. natural killer cell
- Humoral immunity is the part of the adaptive immune system involving: A.cytotoxic T cells killing infected host cells B.neutrophils eating bacteria C.B cells making antibodies to target the invading pathogen D.Your skin cells protecting you from infection with the acidic pH on the surfaceDecreased immunity is a symptom of HIV/AIDS. This is caused by which of the following? Select one: a. HIV destroys antigens. This decreases the possibility of recognizing pathogens in the future. b. HIV destroys memory T cells. If the body is infected again, there is no antibodies to fight an infection. c. HIV attacks the macrophages. Pathogens cannot be destroyed once they enter the body. d. HIV attacks the helper T cells. This allows pathogen cells to enter the body unnoticed.Which of the following is not part of the innate immune system? a. Antibodies b. Skin c. Enzymes d. Neutrophils
