Phagocytosis
- 1. Initiation
- which caused by damage to the tissues, either by
trauma or as a result of microbial multiplication.
- which caused by damage to the tissues, either by
trauma or as a result of microbial multiplication.
- 2. CHemotaxis
- Attraction of WBCs or other cells by
chemicals
- Attraction of WBCs or other cells by
chemicals
- 3. Opsonization
- Coating of a pathogen by substances to enhance phagocytosis
- Opsonins are factors that include
antibodies and complement components
in plasma that coat pathogens and
facilitate phagocytosis
- Opsonins are
also known as
the Fe portion of
antidbody and C3
- Coating of a pathogen by substances to enhance phagocytosis
- 4. Adherence
- Firm contact between phagocyte and microorg
- works well for whole bacteria or
viruses but less for proteins or
encapsulated bacteria
- Firm contact between phagocyte and microorg
- 5. Engulfment
- Into Cytoplasm and enclosed in a vacuole
- Into Cytoplasm and enclosed in a vacuole
- 6. Digestion
- Enzyamtic contents in vacuole destroy the microorg.
- Enzyamtic contents in vacuole destroy the microorg.
- The engulfment of cells or particulate
matter by neutrophils and
macrophages.
- There are two major cells that use Phagocytosis to
remove pathogens in which are Polymorphonuclear cells and Mononuclear cells.
- Polymorphonuclear Cells
- 1. Neutrophils
- 2. Basophils
- 3. Eosinophils
- 3. Eosinophils
- Are smaller cells, more abundant than macrophages
and travel quickly to a site of injury "MOMMIE Reaction
CELL" to gobble up any infecting bacteria that may have
entered/
- 2. Basophils
- 1. Neutrophils
- Mononuclear Cells
- 1. Monocytes in the Plasma
- 2. Macrophages in tissues
- These are large immune cells that patrol
the body looking for invaders or dead cells.
They also travel through bloodstream to
seekout cells to devour
- Also are Efficient Phagocytes
- Also are Efficient Phagocytes
- These are large immune cells that patrol
the body looking for invaders or dead cells.
They also travel through bloodstream to
seekout cells to devour
- DIfferentiated Phagocytes
- Each Monocyte s specific to an organ, they remian in
that organ to patrol and attacak and invaders that enter
that specific organ.
- Each Monocyte s specific to an organ, they remian in
that organ to patrol and attacak and invaders that enter
that specific organ.

remove pathogens in which are Polymorphonuclear cells and Mononuclear cells.
- Extra NOte: Various
molecules of the IS
collaborate with the INNATE
IS's cells
- Is a type of Endocytosis
- Endocystosis is the process in
which a cell absorbs a particle,
molecule, bacterium or other type
of matter by engulfing them.
- Endocystosis is the process in
which a cell absorbs a particle,
molecule, bacterium or other type
of matter by engulfing them.
- Engulfs the larger, solid particles, most the time it is another cell.
- Involves Ingestion and digestion of
- Microorganisms
- Insoluble particles
- Damaged or Dead host cells
- Cell Debris
- Activated clotting Factors
- Activated clotting Factors
- Cell Debris
- Damaged or Dead host cells
- Insoluble particles
- Microorganisms
- The speed of phagocytosis can be increased markedly by bringing
tino action two attachment devices present on the surface of
phagocytic cells:
- Fe Receptor: which binds the Fe portion of antibody molecules, chiefly IgG. The IgG will have attached
the organism via its Fab site.
- Complement Receptor: The third
component of complement (C3) also
binds to organisms and then attaches
to the complement receptor.
- Fe Receptor: which binds the Fe portion of antibody molecules, chiefly IgG. The IgG will have attached
the organism via its Fab site.
- "phago" EAT!!!!!!
