Why does an injured area swell during an inflammatory response?
Blood vessels expand, allowing more blood to flow
Pathogens multiply in the affected area
The immune system is shutting down
The body is rejecting the damaged tissue
What is the main purpose of the inflammatory response?
To slow down the immune system
To help fight off pathogens and start the healing process
To lower body temperature
To reduce the number of white blood cells
What triggers a specific immune response?
The presence of antigens
Low body temperature
Dehydration
The presence of oxygen
How do white blood cells respond to pathogens?
They ignore pathogens and allow them to spread
They create antigens to help the pathogens grow
They destroy pathogens and remember how to fight them in the future
They create toxins to help the pathogen
What is the function of Helper T Cells?
To attack and destroy infected cells
To produce antibodies
To trigger the production of B Cells and Killer T Cells
To remove dead skin cells
What do antibodies do?
Attack body cells
Mark pathogens for destruction
Help pathogens multiply
Prevent the immune system from functioning
What is the difference between active and passive immunity?
Active immunity comes from exposure to a pathogen, while passive immunity comes from another person or animal
Active immunity is only found in children, while passive immunity is only found in adults
Passive immunity lasts longer than active immunity
Active immunity requires medication, while passive immunity does not
What is the purpose of a vaccine?
To weaken the immune system
To introduce antigens that help the body build immunity
To remove harmful bacteria from the body
To immediately cure a disease
How do live-virus vaccines work?
They use completely dead pathogens that cannot trigger immunity
They use modified pathogens that stimulate an immune response without causing the disease
They use chemicals that instantly kill all pathogens in the body
They provide immunity for only one day
How does the body react to the spike protein created by the mRNA vaccine?
It ignores the protein and does nothing
It recognizes the protein as foreign and builds immunity against it
It uses the protein to develop a new type of virus
It destroys its own immune cells
How have vaccines and modern technology impacted infectious diseases?
They have completely eliminated all communicable diseases
They have saved millions of lives but have not stopped all diseases
They have made diseases spread faster
They have only been useful for non-communicable diseases
How is Avian Influenza primarily spread to humans?
Through mosquito bites
Through direct contact with infected birds
Through airborne transmission from humans
Through contaminated drinking water
What makes H1N1 a unique virus?
It is a mix of human, pig, and avian flu viruses
It only affects pigs and cannot infect humans
It spreads only through contaminated food
It was eradicated in 2009
What is the best way to prevent infection from Salmonella and E. Coli?
Avoid eating fruits and vegetables
Cook meat properly and store food safely
Wash hands once a day
Only eat at restaurants
How do recreational water illnesses (RWI) typically spread?
Through insect bites
By inhaling airborne particles
By swallowing or coming into contact with contaminated water
By eating undercooked seafood
How is Lyme Disease transmitted?
Through contaminated water
Through tick bites
Through direct human contact
Through the air
What is the main way humans contract West Nile Virus?
From contaminated food
From mosquito bites
From human-to-human contact
From unclean drinking water
Why does global travel contribute to the spread of disease?
People can carry infections from one country to another in a short time
Traveling strengthens the immune system
Airplanes destroy most bacteria and viruses
Tourists are immune to local diseases
How do pathogens become drug-resistant?
They evolve when exposed to antibiotics and reproduce
They become weaker over time
They are eliminated entirely by antibiotics
They mutate only in laboratory conditions
