What are Wandering Macrophages?

Macrophages that are present in the blood as monocytes, and only transform into macrophages in infected tissue

Are converted into macrophages pre-infection and circulate in the blood

Are converted into macrophages pre-infection and wander between tissues vulnerable to invasion

How is the phagosome destroyed?

Fuses with a lysosome containing lytic enzymes

The temp increases till cell surface proteins denature
