|
How are Transmission Methods possible? |
Physical Contact- Directly touching a person who is infected, Sexual contact, Or coming into contact with infected body fluids (Blood or even droplets in the air from a sneeze) Contaminated Food or Water- Food poisoning, Uncooked meat, Water contaminated because of poor sanitation Infected Animals (Vectors)- Bites from infected animals (Ticks, Fleas, Mosquitoes, and Rabid dogs) |
|
|
What consist of the 1st line of defense? |
Skin, Cilia, Mucus, Lysozymes, and Acidic environment |
|
|
What does Mucus do in the 1st line of defense? |
It traps pathogens and aids in removal |
|
|
What does Lysozymes do in the 1st line of defense? |
Breaks down the cell walls of bacteria |
|
|
What is Mucus? |
Thick liquid |
|
|
What is Lysozymes? |
Enzymes in Saliva, Sweat, Tears, and Mucus |
|
|
Acidic Environment is located where? How acidic is the Acidic environment? What is the result of the Acidic Environment? |
Located in the stomach and skin surface. pH of 2-5 Too acidic for most pathogens |
|
|
What are the Inflammatory Response (2nd line of defense) steps? |
1) Injury occurs allowing pathogens to enter the body 2) Blood vessels near the wound expand 3) White Blood Cells move from the vessels to enter the infected tissues 4) White blood cells engulf and destroy pathogens |
|
|
Inflammatory Response key defenses are what? |
Phagocytes, Fever, and Interferon |
|
|
What is a fever? |
The increase of body temperature to slow down or destroy pathogens |
|
|
What are interferons? |
Proteins produced by viral-infected cells to help other cells resist infection |
|
|
What happens when the 1st and 2nd line of defense failed? |
-The pathogen is able to pass through skin, mucous membrane enzymes, and/or acids -The inflammatory response is unsuccessful is controlling the pathogen, as well |
