Match the following: a) T cells i) produce antibodies b) T-helper
cells ii) involved against viruses c) B cells iii) destroy invaders d) Natural killer iv) increase immunological activity
Answer & explanation
Correct answer: option 1
T cells destroy invaders, and T-helper
cells increase immunological activity. It is
these T-helper cells that are attacked by
the Human Immuno Deficiency Virus
(HIV), the virus causing Acquired Immuno
Deficiency Syndrome (AIDS). B cells
produce antibodies. Natural killer cells are
involved in the fight against both viruses
and tumours.
