What are the four factors that are part of non specific immune response? One of them is inflammation |
Inflammation Phagocytosis Interferons Lysozyme |
|
|
What is lysozyme? |
An enzyme (protein) that disrupts the cell walls of the bacteria by digesting the peptidoglycan . |
|
|
Where is lysozyme found? |
Tears saliva and lysosomes |
|
|
What are interferons? |
Proteins produced by virus infected cells in response to the virus which signals |
|
|
Symptoms of inflammation? |
Redness Swelling Heat |
|
|
When skins tissue is damaged and pierced through what will damaged cells do? |
Damaged cells will release chemical substances such as histamine which act as inflammatory mediators
|
|
|
When skins tissue is damaged and pierced through, what may enter? |
Pathogens |
|
|
When damaged cells release chemical such as histamine to act as inflammatory mediators, what does it cause? |
Increase in blood flow and permeability of the capillary. The area becomes flooded with fluid and blood clotting elements causing swelling and redness |
|
|
What do the tissue cells also release apart some chemicals like histamine to act as inflammatory mediators? |
Chemicals that attract macrophages (white blood cells) to destroy pathogens that enter |
|
|
What happens when phagocytic white blood cells such as macrophage detects a pathogen? |
The cell membrane of the macrophage fuses around the pathogen , trapping it inside phagosome |
|
|
What's phagosome? |
When macrophage's membrane fuses around pathogen , trapping it, the place it's trapped is called phagosome |
|
|
After pathogen is trapped inside phagosome in macrophage, what happens? |
Phagosome fuses with a lysosome which is very acidic and has toxic chemicals and so they form phagolysosome . The bacterium is broken down and digested killing it |
|
|
How does phagolysosome form? |
When phagosome fuses with lysosome |
