Edema/Pain |
|
Plasma (water & proteins) seeping out of the blood vessels during phase 3... a process called
|
Transuation
|
|
Chemical mediators that promote the migration of PMNs from the blood vessel.
This process is called |
Leukotrienes
chemotaxis |
|
Lots of PMNs together
|
purulent exudate/pus

There is now plasma & PMNs outside the blood vessel, but we also need more macrophages. Name the 2 methods |
Macrophages go through mitosis
Macrophages summon more macrophages via chemotaxis |
|
Name the 2 phagocytic cells
|
Macrophages & PMNs
|
|
Besides phagocytic cells, what's the other way to deal with etiologies in acute inflammation?
Resulting S/S |

|
Purpose of plasma coming out of the blood vessel
