,preload the amount of blood returning to the right side of the heart and the muscle
stretch that the volume causes.
-ANP is released when we have this stretch
-the more volume, the more stretch
_________ is released when we have muscle stretch on the ANP (atrial natriuretic peptide)
right side of the heart
afterload the pressure in the aorta and peripheral arteries that the left ventricle has to
pump against to get the blood out
-the left ventricle is pumping against the systemic blood pressure
,blood flow through the heart (DEOXYGENATED)
1-Superior & Inferior Vena Cava
2-Right Atrium
3-Tricuspid Valve
4- Right Ventricle
5-Pulmonary Valve
6-Pulmonary Artery
7- Lungs-pick up oxygen
(OXYGENATED)
8-Pulmonary Veins
9- Left Atrium
10- Mitral Valve (Bicuspid)
11- Left Ventricle
12- Aortic Valve
13-Aorta
14- Body
stretch is good on the right side of the heart (stretch = -hypertrophy
strength), until it stretched TOOOO much!! then the -become weak & floppy
heart will _____________________ -not be able to pump the volume forward
, increased preload = ____________ work of the heart increased
1 multiple choice option
afterload is basically the left ventricle pumping against systemic blood pressure
the ______________________. this pressure is often referred to as
resistance
with hypertension, there is is _________ resistance for the more
left ventricle to pump against
1 multiple choice option
hypertension can eventually lead to heart failure & decreases
pulmonary edema because high afterload
1 multiple choice option
____________________ cardiac output & __________________ forward
flow. plus it wears your heart out because it is having ti
work harder
Stroke volume the amount of blood pumped out of the ventricles with each beat
CO = HR x SV
tissue perfusion is dependent on adequate cardiac true
output
1 multiple choice option
