Cards

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
EDV-ESV
Term
what are the two fast and short types of control for controlling bp
Definition
nervous, and whoremoanal
Term
what is the long term slow control for controlling bp
Definition
kidneys
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
decreased
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
near normal map
Term
chemo receptors location
Definition
aortic and carotid bodies
Term
chemo receptors are sensitive to what 2 compounds in blood
Definition
O2 and CO2
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
epi, norepi
Term
epi increases what two things mainly
Definition
tpr and CO
Term
atrial natriuretic peptide...constrict/dilate and up or down map
Definition
vasodilator...down MAP
Term
ADH (vasopressin)
Definition
vasoconstrictor.

its also ADH...so up the water conservation>^ADH
Term
rennin/angiotensin II
Definition
vasoconstrictor
Term
sympathetic post ganglionic fibers innervate what two things, in terms of the heart
Definition
pacemakers, and cardiac muscle
Term
HTN bp level
Definition
140/90
Term
what effect does htn have on the heart on CO?
Definition
co goes down bc the walls of the ventricles thicken inward
