Innate Immunity Flashcards
What is your third line defense
Adaptive immunity
Summarize what innate immunity does
Lowers the number of pathogens
Does the immune system react to foreign invaders
Yes
Define cytokines
Communication chemicals that promote immune functions
What is the initial immediate defense against foreign invader that is present at birth
Innate immunity
Does innate immunity have the same responses regardless of Invader and regardless of number of exposures
Yes
What is the barrier first-line defense placed at surfaces that’s non-specific
Skin
Define nonspecific
It doesn’t care who the invader is it will kick it out
If breach first line defenses what does the second line defense do
They react to pathogen associated molecular pattern (PAMPs) using pattern recognition receptors on sentinel cells
What is an example of a Second line defense
Phagocytes they have receptors that look for any foreign patterns
What are the components of the first line defenses
Skin and mucous membranes
What are the components of the second line defenses
Leukocytes. Protein substances. Inflammation. Fever
What are the physical barriers of the skin and mucous membranes
Skin and mucous membranes and mucus
What are the flushing actions of the first line defenses
Sweat. Tearing. Peristalsis. Vomiting and diarrhea. Coughing and sneezing. Etc.
What are some of the chemical factors of the first line defenses and their examples
Salt. Acids ex. Stomach, urinary, vagina. Enzymes ex. In your mouth, tears, mucus. Other ex. They find a foreign invader find a ring structure and lyse it.
