EXPH 386 chapter 10 pt. 3 Exam Questions and Answers Fully Solved Latest Update 2025-
2026
Remember CO = - AnswersHR x SV
The volume that fills into the heart after venous return - AnswersPreload
This preload will cause the heart to have _______ _____ which determines _______ -
AnswersEccentric stretch
Contraction
So a ______ preload equals a higher _____ - AnswersHigher
Contraction
This is known as - AnswersFrank Starling method
An increased preload also means a higher _____ - AnswersEDV
Higher EDV -> higher preload -> .......... - AnswersHigher stretch -> higher contraction -> higher SV
-> higher CO
Contraction can also be increased by - AnswersInotropic agents and calcium
Afterload is the - AnswersResistance to ejection
Preload, afterload, and contraction all change - AnswersSV
Cardiac output = Q
It is the amount of blood........ - AnswersPumped by the heart during a 1 minute period (average
5 L/min)
Q measures the ________ _______ of the circulatory system - AnswersFunctional capacity
Fick Equation: the relationship between VO2, and the difference in ___ content in ARTERIAL and
VENOUS blood to find ____ - AnswersOxygen
CO
, Fick equation: - AnswersCO = VO2 / (aO2-vO2) Then x100
Case study:
250 mL O2 consumed total
20 mL O2 in arteries
15 mL O2 in veins - AnswersQ = 250/5 = 50
x100
Q = 5000 mL a minute
To record these measurements of O2 in the arteries can be very invasive, so it can also be
measured by breathing tests, such as _____ _____ _____ and recording ____ instead of O2 -
AnswersOpen circuit spirometry
CO2
This equation is the same just _____ is replaced where O2 is - AnswersCO2
Echocardiograms can be used to get _____ by finding the ____ and _____ and subtracting them -
AnswersSV
EDV
ESV
Looking at untrained vs trained at rest:
At REST ____ of blood is pumped by the heart regardless of physical condition - Answers5L (Q)
