Term
| mean arterial pressure formula (MAP |
|
Definition
| cardiac output*total peripheral resistance |
|
|
Term
| cardiac output (CO) formula |
|
Definition
| stroke volume x heart rate |
|
|
Term
| stoke volume (SV) formula |
|
Definition
|
|
Term
| what are the two fast and short types of control for controlling bp |
|
Definition
|
|
Term
| what is the long term slow control for controlling bp |
|
Definition
|
|
Term
| what part of the brain contains the excitatory vasomotor center, what type of innervation does it control |
|
Definition
| lateral medulla, sym stim |
|
|
Term
| what part of the brain holds the inhibitory control for bp, and what "type" of innervation does it control |
|
Definition
| medial medulla, controls para symp stim, via vagus nerve |
|
|
Term
| the excitatory vasomotor center causes peripheral vaso constriction or dilation. and it also causes increased excitation in what 2 qualities |
|
Definition
| constriction, rate and strength |
|
|
Term
| parasympathetic stimulation leads too decreased/increased HR? |
|
Definition
|
|
Term
| 2 places baroreceptors are located |
|
Definition
| carotid sinuses, aortal arch |
|
|
Term
| when arterial pressure goes up, do the baroreceptors fire more or less? and depending on how they fire..what does that lead an increase to? |
|
Definition
| well they would fire more, depress symp stim and excite parasymp stim to heart |
|
|
Term
| where does maximal baroreceptor sensitivity occur in terms of MAP |
|
Definition
|
|
Term
|
Definition
| aortic and carotid bodies |
|
|
Term
| chemo receptors are sensitive to what 2 compounds in blood |
|
Definition
|
|
Term
| so if the chem receptors detect decreased o2, more co2, and decreased pH what will happen |
|
Definition
| the excitatory cardiac control centers will be stimed, leading to ^TPR, and increased CO....which in turn increases MAP overall |
|
|
Term
| 2 whoremoans that come from adrenal medulla |
|
Definition
|
|
Term
| epi increases what two things mainly |
|
Definition
|
|
Term
| atrial natriuretic peptide...constrict/dilate and up or down map |
|
Definition
|
|
Term
|
Definition
vasoconstrictor.
its also ADH...so up the water conservation>^ADH |

Definition
|
|
Term
| sympathetic post ganglionic fibers innervate what two things, in terms of the heart |
|
Definition
| pacemakers, and cardiac muscle |
|
|
Term
|
Definition
|
|
Term
| what effect does htn have on the heart on CO? |
|
Definition
| co goes down bc the walls of the ventricles thicken inward |
