Immune System Quiz

1. The hairs of the respiratory tract which prevent dust and smoke from entering the respiratory tract are:
A mucus
B villi
C cilia
2. A non-specific form of defence against disease is:
A intact skin
B hydrochloric acid in stomach
C both of the above
3. The body defences that do not specifically work against a particular invading antigen are called:
A pathogenic
B specific
C non-specific
4. The white blood cells which form part of the non-specific defence against disease are the:
A antibodies
B plasma cells
C phagocytes
5. The form of defence that specifically acts against a particular foreign particle is called:
A pathogenic
B specific
C antibiotic
6. The foreign particle that stimulates an immune response is called the:
A antibody
B antigen
C immunoglobulin
7. The lock and key model of how an antigen works describes the antigen as the key and what chemical as the lock?
A T cell
B antibody
C lymph gland
8. The white blood cells responsible for antibody production are the:
A T cells
B D cells
C B cells
9. A chemical produced naturally in small quantities by the human body and that can act against viruses is:
Aantigenic
Binterferon
Cvaccination
10. Immunisation may be obtained through:
Abreast milk
Bvaccination
Cboth of the above
11. T cells are produced by the:
Athyroid gland
Bthymus gland
Cparathyroid gland
12. What non-specific first lines of defence does the body have against invading pathogens?
Aintact skin, ciliated membranes
Btears, stomach acid, phagocytes
Cboth of the above
13. An antibody is:
Aa foreign particle that triggers an immune response
Ba specific chemical produced by B cells
Cthe cell that produces antibodies
14. The immune system responds more rapidly to an antigen which it has encountered before because:
Anon-specific defences of the human body are diverse
Bnon-specific defences such as B and T cells act rapidly
CB cells previously identified the chemical structure of the foreign particle, retained a 'memory' of it, and can produce antibodies quickly to neutralise it
15. Why must a heart transplant recipient continue to take immuno-suppressant drugs for life?
AThe transplanted heart rejects the immune system.
BThe transplant recipient requires repeated vitamin boosters.
CThe transplanted heart is foreign and can trigger an immune response to reject it.
