All of the following factors would be expected to increase
stroke volume EXCEPT ________.
Group of answer choices
increased end diastolic volume
increased afterload
decreased end systolic volume
increased venous return
a. Describe the typical postural alignment of upright standing
posture when observing a person from each of the three planes.
b. The plantar flexors are considered a postural control muscles
during upright standing posture. Describe how this muscle group
function during upright standing position.
You know that stroke volume is the difference between End
Diastolic Volume and End Systolic volume. The attending physician
in the Cath lab just told you that your patient’s End Systolic
Volume has decreased, and their stroke volume has increased. She
asks you the following questions. How would you respond?
a.What did the heart do to lower the End Systolic
Volume?
b.What two possibilities (mechanisms) could the heart have
used to achieve the increase in stroke volume and lower End...
(a) Draw and discuss the ventricular function (end-diastolic
volume versus stroke volume) curve to illustrate the
Frank-Starling mechanism. (b) Explain how sympathetic
stimulation, increased pre-load or increased after- load might
affect this curve respectively
1.(a)When a person exercises, one of the physiological
responses is an increase in blood flow. In terms of the nervous
system and various blood vessels, describe what’s
happening.
(b)How did dorsal vessels work in
arthropods?
(c)Mollusk hearts compared to fish hearts?
(d)True or false, all vertebrate hearts start off as two
chambered hearts in the embryo.
Why does the hematocrit rise when a person is
dehydrated?
A.
An increase in plasma electrolyte concentration is recorded on
the hematocrit.
B.
Edema occurs, meaning water moves from the circulation into the
interstitial fluid.
C.
Sweat is mainly water and when the water content of blood
decreases the hematocrit is increased.
D.
Sweat is mainly water and when the water content of blood
decreases the hematocrit is decreased.
2. What values are correct for cation concentrations
in plasma?
A....
The nurse working on a cardiac care unit is caring for a patient
whose stroke volume has increased. The nurse is aware that
afterload influences a patient's stroke volume. The nurse
recognizes that afterload is increased when which is present?
a. sepsis
b. venous congestion
c. arterial vasodilation
d. hypertension
