Innate Immune Response Flashcards
Serves as the frontline of defense by the body against pathogens and invaders
Involves surface barriers and non-specific immunity cells
Innate Immune System
Already present at birth
Serves as barrier for the entry and spread of microorganisms in the body
Action happens at the same speed every time there is an invader
Innate Defenses
is the first line of defense of the body.
skin
The skin is equipped with…?
impenetrable epithelium
when the skin is ———— it becomes vulnerable to ————–
wounded , pathogens
are internal surfaces that protect epithelial cells from damage
Mucosae
are hairlike structures present in epithelial cells.
It serves to clean the tract by removing the mucus.
Cilia
Respond to bacterial infections and the formation of tumors.
Capable of targeting pathogens.
Tags any infected cells that need to be destroyed
Natural killer cells
The process of engulfing pathogens in order to destroy them
Phagocytosis
Provides immediate actions to protect the body against pathogens
Innate Immune Response
Two parts of innate immune response
Recognition of pathogen, effector mechanism
- soluble proteins and cell-surface receptors recognize and bind with the pathogen
Recognition of pathogen
cells engulf, kill or attack pathogens
Effector Mechanism
An immune response in the presence of pathogens
Caused by white blood cells and discharged substances
Inflammation
