Which of the following cells take part in phagocyotsis
Macrophages
Neutrphils
Lymphocytes
Eosinophils
Basophils
Macrophages predominate the early infection
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
Fixed Macrophages remain in the tissue permanently after conversion
Fixed macrophages enter the tissue and convert before infection
What stage of phagocytosis is being shown here?
Pseudopodia extension
Pathogen consumption
Chemotaxis
The vesicle inside the phagocyte containing the pathogen is known as a phagosome
How is the phagosome destroyed?
The basic pH breaks it down
Fuses with a lysosome containing lytic enzymes
The temp increases till cell surface proteins denature
Antigen Presenting Cells are phagocytes that keep antigens for presentation on their TCR's
