Page 9: Body Response Flashcards
To maintain homeostasis in an environment rich in pathogenic bacteria, fungi, parasites, and viruses (microbial stressors) an animal must _ entry using physical and physiological barriers, _ pathogen as non-self if barriers are breached, restore homeostasis by _ to eliminate pathogen
- Prevent
- Recognize
- Responding
If the animal is able to achieve prevention, recognition, and response the animal will remain _ and develop enhanced long-term _ against the pathogen
productive, protection
If the animal is not able to eliminate pathogen _ will occur
disease
Disease is a welfare issue and can affect _ and possibly lead to _, may be a _ _ issue
productivity, death, human health
Disease is an _ or _ that prevents the body or mind from functioning _
illness, condition, normally
Animals host microbial populations on skin, and mucosal surfaces. Under normal condition the host learns to tolerate these microbes and has an important _ relationship with them
symbiotic
What does the host do for the microbes?
Provides nutrients and environment that supports microbe survival
What do the microbes do for the host
Make nutrients available for host use and protect against pathogenic microbes
If tolerance to symbiotic microbes doesn’t develop normally at a young age it can lead to _
disease
Recognition and response to a pathogen is known as the
non-self
Recognition and response to tumour cells is known as the
modified self
To tolerate non-self microbes is facilitated by the _ system
immune
The immune system is comprised of branches the _ and _ immune system
innate, adaptive
The _ immune system is highly conserved across species and is the first to be activated in response to _ _
innate, microbial stressors
Immunity is the protection provided by the immune system to resist _ _
microbial infection
