Question 1

Cardiac Output

Answer 1

The amount of blood pumped out of the left ventricle each MINUTE

Question 2

Stroke Volume (SV)

Answer 2

(EDV-ESV)

Volume of blood at the end of relaxation minus the blood remaining in the ventricle after ejection

Question 3

CO Equation

Answer 3

CO = SV x HR

Question 4

Preload

Answer 4

Volume of blood in heart

Stretch of cardiac muscle cells before contraction
chamber volume prior to contration

Question 5

Afterload

Answer 5

Force opposing ejection of the blood from the ventricle

-resistance that must be overcome in order to eject blood from the chamber

Question 6

Hypovolemia

Answer 6

Will have less ventricular fulling, reduced preload, and lower stroke volume

Question 7

Frank-Starling Law

Answer 7

(preload)

-An increase in resting muscle fiber length results in greater muscle tension

Question 8

Intracellular fluid

Answer 8

Inside the cells

Question 9

Interstitial fluid

Answer 9

Surround cells

Question 10

Extracellular fluid

Answer 10

Inside the capillary

Question 11

Forward effects of LVF

Answer 11

Diminished perfusion to circulatory system
-Activates neurohormonal response (RAAS,ADH, SNS)

-INC BLOOD VOLUME + BLOOD PRESSURE
