Fill In The Blanks - Write INCREASE OR DECREASE, or REMAINS UNCHANGED
21. If blood vessels are vasoconstricted, afterload to the ventricle
increases and stroke volume decreases
22. If afterload increases, stroke volume decreases
23. As preload decreases, stroke volume decreases
24. Increased blood volume increases preload
25. If stroke volume decreases, heart rate increases to compensate
and maintain cardiac output
26. If stroke volume remains the same, a decrease in heart rate will create a
decrease in cardiac output
27. Reduced ventricular filling results in decreased preload and
decreased stroke volume
28. Stimulation of the parasympathetic nervous system decreases heart rate
and decreases contractility
29. Vasodilation leads to a decrease in afterload and an
increase in stroke volume
30. Aerobic exercise increases systolic blood pressure and
decreases diastolic blood pressure because blood flow away from the
heart increases
31. Resistance training increases systolic blood pressure and
increases diastolic blood pressure because vasoconstriction
32. Increases in sympathetic activity increases calcium concentration
in cardiac muscle cells increases the strength of the contraction
33. Increases in contractility increases stroke volume
34. With dehydration there are decreases in blood volume and flow thus
decreases stroke volume and increases in heart
rate
