You are a doctor and Little Billy is in your office with the flu. His mother wants you to prescribe an antibiotic. Which would be the best response?
"Absolutely, get that kid an antibiotic!"
"Actually, he just needs to take a painkiller."
"Unfortunately, antibiotics do not work against viruses like the flu."
"Give him a vaccine and he will feel better right away!"
Active immunity is when
You produce your own antibodies to a disease
You are given antibodies to a disease
You are immune to any type of disease
Macrophages invade your lymphatic system and shield you from ever falling sick
Passive immunity is when
You produce your own antibodies to a disease
You are given antibodies to a disease
You are immune to any type of disease
Macrophages invade your lymphatic system and shield you from ever falling sick
Active immunity lasts for a ____________ time. Passive immunity lasts for a ___________ time.
Long; Short
Life; Life
Hours; Long
Short; Long
Doctors sometimes use a vaccine to prepare the body to defend itself against future infections. These vaccines most often contain
antibodies
antibiotics
white blood cells
weakened pathogens
A new vaccine was developed and then tested on a large sample of individuals. This new vaccine will be considered effective if it helps prepare the body to fight future invasion by
inhibiting the response of red blood cells
stimulating the reproduction of microbes
inhibiting the action of immune cells
stimulating the production of antibodies
TRUE or FALSE.
When child B is administered these vaccines, child B will form antigens against both diseases
TRUE
FALSE
An immune response is primarily due to the body’s white blood cells recognizing
a hormone imbalance
abiotic organisms
foreign antigens
known antibiotics
WHAT DOES THE "A" IN AIDS STAND FOR?
AUTO
ACQUIRED
AWESOME
Which cells does HIV (AIDS virus) target and destroy during infection?
Killer T cells
Helper T cells
Macrophages
Memory B cells
B cells
The patient develops AIDS from an HIV infection when the T-cell count drops below
100/ul blood
350/ul blood
200/ul blood
500/ul blood
What can you infer about the medicines called antihistamines?
They cure people's allergies
They prevent all asthma attacks
They cause the immune system to shut down
They reduce the severity of allergy symptoms
A histamine response is most often characterized by:
Fainting
Fever
Swelling
Death
Scientists are developing a malaria vaccine that would most likely contain
weakened drugs used to treat the symptoms of malaria
white blood cells from the malaria-infected individuals
a weakened form of the malaria-causing organism
antibodies made from the malaria-causing organism
Every time a child visited a cousin who has two cats, the child's eyes turned red, itched, and began to water. Then, the child began to have trouble breathing. it is most likely that the child reacted this way because
normally harmless antigens stimulated the immune system
it is difficult for the respiratory system to filter cat antigens out of the inhaled air
cat antigens are a health hazard, since they always cause disease
cat antigens stop the immune system from making antibodies, so bacteria cause these responses
Which structure normally stimulates an allergic response?
A, only
B, only
C, only
A, B, C
When people receive organ transplants, they often need to take medications that decrease immune responses because
transplanted organs contain antigens that can trigger white blood cell activity
hormones present in replacement organs prevent the synthesis of antibiotics
transplanted organs produce their own antibiotics
antigens present in these organs attack antibodies already present in the blood
When the immune system of a person starts to attack their own body cells that it's supposed to protect, then this can be classified as
immune disorder
autoimmune disease
multiple sclerosis
rheumatoid arthritis
Autoimmune diseases can be characterized as the immune system failing to distinguish "self" from (a) .
Rheumatoid arthritis occurs when the immune system targets an individual's own tissues as a foreign antigen (like a pathogen) and mark it for destruction.
What tissue is affected?
nerves
cartilage
digestive system
skin
Multiple Sclerosis occurs when the immune system targets an individual's own tissues as a foreign antigen (like a pathogen) and mark it for destruction.
What tissue is affected?
nerves
cartilage
digestive system
skin
Crohn's Disease occurs when the immune system targets an individual's own tissues as a foreign antigen (like a pathogen) and mark it for destruction.
What tissue is affected?
nerves
