- What is an example of
negative feeback of the
homeostatic regulation?
Negative fresponse to a eedback hgiven action gappens when theenerates a (^) n
effect that inhibits that action. Forexample, when the carbon dioxide (^)
concentration in blood is high the
pulmonary resthe CO piration is stimulated for
expiration. H^2 excessyperventilation, to be expelled through however,^
lowers the in blood too much carbon dioxide concentrationgenerating a negative (^)
feedback that commaof the respiratory frequency.nds the reduction
Negative fmechanism ofeedback is th homeostasise main and it occurs (^)
in a variety of processes, such as in
blood pressure muscle contraction,control, glyc etc. emic control,
- What is an example of
positive feedback of the
homeostatic regulation?
In positive fby an action stimulateseedback the effect caused the action even (^)
more. This is a rarer mechanism of the
homeostatic regulation.
An example of positive feedback isblood clotting process in which each the
chemical reaction produces enzymes
that catalyze ththe formation of fibrin. Te following herefore thereaction until
products of the antecedent chemical
reactionsequilibrium o are consumef each reactiond and the is
dislocated towards the production of
more enzymes (a positive feedback).
