Health |
A state of mental and physical well being |
|
|
3 factors of poor health |
Diet, Stress, Life situations |
|
|
Communicable disease |
Infectious diseases and are caused by microorganisms called pathogens. |
|
|
What are the four types of pathogens |
Viruses, Bacteria, Protists, Fungi |
|
|
Virus |
• Hijacks cells • Gets inside cell and uses host cells resources to reproduce ( can damage or kill cell) |
|
|
Bacteria |
•Gets inside body and releases toxins ( chemical that damages tissues) |
