Which of the following descriptions is correct?
Natural Passive Immunity Example: Antibodies injected into the blood
Artificial Active Immunity Example: Manufacturing antibodies after contracting disease
Active Passive Immunity Example: Antibodies crossing the placenta of a foetus
Natural Active Immunity Example: Manufacturing antibodies after contracting a disease
Pyrogens are substances that trigger the hypothalamus to bring about
inflammation
an immune response
a fever
swelling
Which of the following is a possible reason why Australians choose not the complete immunisation programs for their children?
cannot afford the cost of the vaccine
a religious objection to medical technologies
believe vaccines increase their children's immunity to diseases
forget to visit the doctor at the time a vaccination is required
As part of the first line of defence in the human immune system, naturally-occurring barriers to invading pathogens include
lysozymes in tears.
the production of antibodies.
the engulfing of pathogens by phagocytes.
inflammation at the site of infection.
The following statements describe how vaccines, antibodies and/or antiviral medications work.
I. treat viruses & bacterial infections
II. treat only viral infections
III. can provide broad-spectrum treatment to a variety of pathogens
IV. are specific to each pathogen
V. are only effective at the time when taken
VI. can provide lasting immunity
Which of the following statements are true for antiviral medications?
I, III & V
II, III & VI
II, IV & V
I, IV & VI
Gemma is scratched on the leg by her cat. The next day, she notices an inflammatory response occurring around the area where she has been scratched. In the inflamed area
the skin will become swollen and cold to touch.
red blood cells will release histamine.
mast cells will produce pus.
there will be increased blood flow.
Which of the following contains substances that act as external defence mechanisms against pathogens?
cebum, lysozyme, sweat, cerumen
cebum, lymphocytes, sweat, lysozyme
antibodies, lysozyme, lymphocute, T-cells
lysozyme, lymphocyte, sweat, cilia
Which of the following best describes an airborne mode of transmission of a pathogen?
exchange of blood and other body fluids by a used syringe
contact with contaminated vomit while cleaning it up
transmission from mother to baby via breastfeeding
sharing an elevator with an infected person who is sneezing
Antibiotic drugs differ in their specificity to pathogens and as such, are often classified as
bactericidal & bacteriostatic antibiotics
multiple drug-resistant and total drug-resistant antibiotics
broad-spectrum & narrow-spectrum antibiotics
antiviral & antifungal antibiotics
Antibiotics are ineffective against viruses because viruses
keep changing their external protein coat
are able to disguise themselves in the host cell membrane
are not living cells and thus do not metabolise
can change antibiotics into useful food substnaces
A key component of cell-mediated immunity is the body's production of
antigens
antibodies
memory B cells
killer T cells
Which is the following comparisons between B cells & T cells is correct?
B cells: Originate in the bone marrow
T cells: Originate in the thyroid
B cells: Differentiate into killer, suppressor and helper cells
T cells: Differentiate into plasma cells
B cells: Form the cells needed for antibody-mediated immunity
T cells: Form the cells needed for cell-mediated immunity
B cells: Can inhibit the immune system
T cells: Can react against transplanted organs
When re-infected by the same antigen, the immune response in quicker. This is due to the presence of
memory cells
killer T-cells
B-cells
helper T-cells
Which of the following is not a type of bacteria?
cocci
spirilla
bacilli
vibrato
Bacteriostatic antibiotics
prevent bacteria from reproducing by disrupting bacterial protein synthesis
change the structure of cell wall or cell membrane
disrupt the action of enzymes
prevent a virus from uncoating
Select the best description of a virus
a non-cellular living organism
a small form of bacteria
a cell at the boundary between the living & non-living
a abiotic organism containing either RNA or DNA
Dermatitis is inflammation of the skin. Choose the best description of an inflammatory response.
An internal non-specific defence as a response to invading pathogens
an internal non-specific defence as a response to tissue damage
an antibody-mediated specific response to infection
a cell-mediated specific response to infection
Pathogens are neutralised and elimated during acute inflammatory responses. All of the following are stages in the inflammatory response except
clots, due to release of heparin, form to limit pathogen spread
increased number of leukocytes arrive at site due to increased blood flow
temperature of site increases to inhibit pathogen growth due to blood leakage into tissue
pathogens engulf and digest dead cells & pathogens producing pus
