Host Immune Response Flashcards
Two types of immune defenses have.
Innate immune defenses.
acquirer immune defenses.
Th immune defenses of the body rely on ____.
Humoral
Cell-mediated mechanism
This response happens when the body detects and eliminates pathogens through a non-specific mechanism.
Innate response
Example of innate response.
Phagocytosis by macrophages and dendric cells
How do macrophages and dendritic cells eliminate pathogen.
Through oxidative killing and the use of toxic peptides
What immune mechanisms are required to kill intracellular parasites?
Cell- mediated immune mechanism
T or F
Natural killer cells are acquired cell mediated immunity, and T lymphocytes are non-specific.
False
Natural killer cells (non-specific)
T-lypmhocytes (acquired)
