1
Q

A
organisms corrective response to an environmental change
2
Q
when being cold
A
shivering (warms u up)
3
Q
when being hot
A
sweating (cools u down)
4
Q
Negative feedback mechanism
A
most common type of dynamic equilibrium
5
Q
example of negative feedback mechanism
A
thyroid [thyroxin] decreases then pituitary gland secretes TSH. TSH increases thyroxin production then increase thyroxin decrease TSH production
6
Q
TSH
A
thyroxin stimulated hormone
7
Q
Disease
A
breakdown of dynamic equilibrium (internal and external factors)
8
Q
internal factor
A
genetic/hereditary -> “non-infectious”
9
Q
external factor
A
microbes (pathogen) -> infectious
