1 of 32

Other questions in this quiz

2. Why are the respiratory and digestive systems the most common sites of entry for pathogens?

  • The immune system is weak in these systems
  • They are easy for the microorganisms to colonise
  • Diffusion takes place here - so they have a large surface area, have a good blood supply and are thin so that the pathogens can easily attach to them and penetrate
  • They are large organs

3. The purpose of enzymes is to break down the invading pathogens

  • True
  • False

4. How do pathogens cause disease?

  • by resisting the host
  • by damaging host tissues and producing toxins
  • by colonising the host

5. How is a person defined as being infected?

  • If a pathogen causes damage to the host tissue
  • If a pathogen gains entry to the host and colonises its tissue
  • If a pathogen resists the defences of the host
