Question: 5 what is an example of a soluble defensive factor...

Question details

5) What is an example of a soluble defensive factor produced by the immune system?

A T cells.
B B cells.
C NK cells.
D Antibodies.

6) Which one of the following cells is most capable of killing your own cells if they become infected with a virus?

A Dendritic cells
B B cells
C Natural killer cells
D Basophils

7) How can your immune system be trained to protect you against a pathogen that you have
never been infected with?

A Inspirational videos.
B By infection with that pathogen.
C Drinking lots of coffee and wheat grass.
D Vaccination.

8) Why are innate immune responses faster than adaptive responses?

A Because innate cells are already fully developed whereas adaptive cells must undergo a differentiation process before they can participate in defending against a pathogen.
B Because soluble innate defensive factors are already present in your blood and interstitial fluids whereas soluble adaptive factors can only be produced after infection (or vaccination).
C The number of innate cells capable of recognizing and responding to an infection is much larger at any given moment than the number of similarly capable adaptive cells.
D All are correct
E None are correct

9)Which one of the following is not a sentinel cell?

A Mast cell
B Monocyte
C Macrophage
D Dendritic cell

10) Which one of the following is an innate cell that is capable of producing antibody?

A ILC-1
B Gamma-delta T cell
C B-1 cell
D B-2 cell
E ILC-2
