Fighting Disease Flashcards
What type of pathogen do antibiotics fight against?
Bacteria
Name three ways pathogens can enter the body.
Any Between: Saliva, sexual intercourse, blood, insects, open wounds, bodily fluids and through the air.
Name the type of drug that relieves symptoms, but doesn’t kill the pathogen.
Painkillers - Examples include aspirin.
Name the two drugs that fight against bacteria and viruses.
Antibiotics and antiviral drugs.
Name the substance that fights against toxins.
Antitoxins
Name the two types of white blood cell and what they do.
Lymphocytes produce antigens which attach to the surface of the pathogen, while phagocytes engulf the pathogens.
Name three viral diseases.
Measles, HIV and Tobacco Mosaic Virus (TMV).
Name a fungal disease and how does it effect the thing it infects.
Rose black spot effects rose plants by making purple or black spots to develop on the leaves of the plant. It slows down photosynthesis by turning leaves yellow and making them fall off.
What is a common disease caused by a protist?
Malaria is caused by a protist and is spread by mosquitoes.
Which are smaller, Bacteria or viruses?
Viruses.
How do viruses spread?
The virus injects itself into a cell, and reproduces until the cell bursts, before moving on to infect other cells.
What is a very recent problem surrounding antibiotics?
Doctors are giving too many people antibiotics, and they aren’t finishing the course, thus causing antibiotic resistance among the bacteria.
Name one bacterial infection that is resistant to a powerful antibiotic.
MRSA, a wound infection.
What do people have to prevent catching diseases?
Barriers include skin, mucus (Produced by cillia) and saliva.
What is injected into the body during a vaccine?
A weak, dead or inactive form of a pathogen.
How do vaccines work?
Vaccines work by injecting a dead, inactive or weak form of a pathogen into the body. The white blood cells in your immune system will find the correct antibody to kill the pathogen, and if a live version of the pathogen finds its way into the system, the white blood cells will know what antibody to produce.
