b1
b2 a1: increased intracellular Ca |
|
|
what receptors decrease HR
|
M2
|
|
|
what receptors make NO at endothelial cells
|
M3
|
|
|
what receptor decreases the rate of AV conduction
|
M2
|
|
|
what receptors do arteriolar constriction
|
a1
|
|
|
what receptors increase HR
|
B1
B2 |
|
|
what does arteriolar dilation
|
B2
M3 |
|
|
what increases rate of vent relaxation
|
B1
B2 |
|
|
how does a decrease in HR affect aortic pressure
|
syst and diast are decreased
**PP is the same but MAP decreases |
|
|
how does an increase in SV affect aortic diastolic P
|
stays the same
Aortic SP, PP, and MAP all increase |
|
|
what does endothelin do
|
constroctor
decreases BF |
|
|
what are the metabolites for:
heart brain sk mm |
Heart: CO2, O2, NO, H+ adenosine
Brain: CO2, NO, H, K, Adenosine Sk mm: adenosine, K, lactate |
|
|
name 4 similiar metabolites for brain and heart. name 1 different
|
BOTH: CO2. NO, H, Adenosine
Heart: o2 Brian: K sk mm: K, Adenosine, Lactate |
|
|
what SNS receptors are present in:
coronary brian sk mm |
coronary: a1, b2
brain: a1 sk: a1, b2 |
|
|
baroreceptors are activated when...
decreased activity when... |
increased activity when BP increases
decreased activity when BP decreases |
|
|
what does the vasomotor center do?
|
**baroreceptor and VMC have inverse relationship, when BR fire lots (increased P) there will be a decrease in VMC, so that SNS decreases and PNS increases
|
|
|
is SNS the same as VMC or BR
|
VMC
|
|
|
baroreceptor activity and NTS, VMC
|
BR is same as NTS
BR is opposite of VMC |
|
|
*********if BR increases (increased BP), VMC decreases, SNS decreases, PNS increases
|
IF BR DECREASES (lower BP), VMC increases, SNS increases, PNS decreases
|
|
|
what does venoconstricion do to unstressed volume?
|
decreases
|
