Q

What is disease and what are the two groups its divided into?

A
  1. Does not allow the body to function normally
  2. Can affect individual organs or an entire body system

Q

How are pathogens transmitted?

6

A 
In the air
In water
In food
In body fluids like saliva, blood, semen
By touching
By another organism like the mosquito
These transmitters are called vectors

Q

Name the ways that bacteria can interact in the human body. Remember that these can be overlapping.
4

A
  1. Some bacteria are entirely adapted to the pathogenic way of life in humans. They are never part of the normal flora but may cause subclinical infection (not part of the body and come in just to be infectious)
  2. Some bacteria which are part of the normal flora acquire extra virulence factors making them pathogenic (something makes normal floura infectious)
  3. Some bacteria from the normal flora can cause disease if they gain access to deep tissues by trauma, surgery, lines especially if associated with a foreign body (bacteria get to parts of the body they arent supposed to be through trauma)
  4. In immuno-crompromised patients many free-living bacteria and components of the normal flora can cause disease (overgrowth) especially if introduced into deep tissues
    (overgrowth of normal bacteria in immunocomprimised patients)

Q

4 ways pathogens make us sick?

A
  1. Bacteria produce poisons that cause cell death
  2. Viruses use our cells to reproduce and then cause cell death
  3. Fungi grow and produce toxins
  4. Parasites live and grow in our body destroying tissue

Q

What is the defintion of headaches or (cephalgia)?

How is the brain involved in headaches?

A

Is a pain anywhere in the region of the head or neck. It can be a symptom of a number of different conditions of the head and neck. –The brain tissue itself is not sensitive to pain because it lacks pain receptors.
