local input
|
effects increase or decrease HR
exercise: increase CO2>dec O2> increase lactic acid>decrease PH>vasodilation>decrease pressure>increase CO |
|
|
bainbridge reflex
|
response to stretch in right atria
stim sympathetic to increase HR and contractivity |
|
|
chemoreflex
|
increase heart rate and ventilation in response to increase CO2 in carotid and aortic body
|
|
|
temperature
|
increase temperature > increase heart rate to cool the blood
|
|
|
baroreflex
|
receptors located in heart, great vessels (prom in internal carotid), intrathoracic, and cervical vessels.
It response to pressure and decreases HR, contractivity and causes vasodialtion. It does that by stimulating vagus N (parasympathetic system) with decrease pressure, baroreceptor activates sympathetics to vasoconstrict> increase BP; inotropy> increase SV/CO; increase HR> increase CO |
