Inflammation is a response to ______________.

tissue injury

Vasodilation is beneficial during an inflammatory response because it:

Could be eliminated from causing infection by the urination..

Is resistant to lysozyme.

Could be lysed by complement.

Wandering macrophages are found:

moving through the tissue

__________________ are phagocytic.  (Select all that apply.)

Neutrophils

Macrophages

Put the stages of phagocytosis in order.

1: Macrophage adheres to a microbe             

2: Ingestion             

3: Phagosome formation             

4: Phagolysosome formation             

5: Formation of residual body
