1)Pattern recognition is involved in innate immunity.             

 2. Defensins are short antimicrobial peptides found within mucous membranes and phagocytes.

 3. White blood cells also called leukocytes are important in immunity.

4.         Mast cells are only found in the blood.            

5.         Lymphocytes are the cells primarily responsible for the adaptive immune responses.         

6.         All pathways of complement activation follow the same sequence after C3.            

7.         Gram-negative bacteria are less susceptible to complement lysis than Gram-positive bacteria.     

8.         Interferon directly interacts with and destroys viruses.          

9.         Neutrophils are the second phagocytic cell to respond to an infection.         

10.       Fever often enhances bacterial survival during an infection.
