integration of cardiovascular function (regulation) Flashcards
is the chnage in pressure different for each organ
No, same change in presure
what determines what organs get the highest flow
The organs with the smallest resistance get the highest flow
what determines MEan systemic arteriall pressure
Cardiac output
Total peripheral resistnace
what is total peripheral resistnace
The sum of the resistance to flow offered by all the systemic blood vessels
what is the equation for MAP
COx TPR
how does one chnage map
chnage cardiac output
Change total peripheral resistance
what does a drop in MAP lead to
a drop in organ to blood flow
what does the body adjust to protect mean arterial blood pressure
Compensatory changes
what does Flow equal
change in pressure/ resistance
what is flow equal to in the body
Cardiac output
what is resistnace equal to in the body
TPR
what happens to MAP and organs if blood loss
Reduces MAP and leads to irreversible and fast damage to brain and heart
what is the receptor that helps to control homeostatic maintenance of MAP
baroreceptor neurons
what do baroreceptors do
Constantly monitor pressure of aortic arch and carotid sinuses to maintain MAP
what is the normal resting MAP
93ish
