Defensive Components Of Blood Flashcards
Specialized white blood cells, phagocytes include (3)
Neutrophils
Polymorphs
Monocytes
Function of neutrophils, polymorphs, and monocytes is to _
Phagocytose invading particles
Phagocytosis involves engulfing and breaking them up through a process of _
Intercellular digestion
Phagocytes spread from blood vessels to tissue where they are best placed to _
Attack invading microbes
_ short lived
Polymorphs
_ long-lasting
Monocytes
Monocytes turn into _
Macrophages
Macrophages create _ around microbes
Zone of inflammation
Zone of inflammation around microbes helps limit _
Spread
In the zone of inflammation, macrophages _
Engulf microbes
T lymphocytes classified in three groups (3)
Helper T cells
Cytotoxic T-cells
Suppressor T-cells
Lymphoid cell three forms are T-lymphocytes, B-lymphocytes, and _
Interferons
T-lymphocytes very effective at _
Attacking viruses
B-lymphocytes produce _
Antibodies against microbes
_ recognize human cells that have been overtaken by viruses as intracellular factories and destroy them (2)
Killer cells
Natural killer cells (NK)
Interferons are chemical agents which are produced by _
Cells infected by viruses and T-lymphocytes
Interferons flow through bloodstream, activating _ and providing defense against viruses
NK cells
Complement consist of _
20 proteins
When infections occur, complements 20 proteins work together and attack bacteria and organize _ around infected area
Inflammation
_ attach to bacteria and disable them in early stages of infection
Acute phase proteins
Eosinophils inactivate parasites by _
Binding to them and releasing a toxic protein
Lymphocytes normally attack invaders with _ rather than phagocytosis
Enzymes
