Understanding Hemodynamics: A Comprehensive Quiz
Test your knowledge on the intricate relationship between blood pressure, perfusion, and cardiovascular health. This quiz focuses on key concepts surrounding hemodynamics and associated physiological mechanisms.
- Explore topics from baroreceptors to heart failure.
- Perfect for students and professionals in health sciences.
- Engage with thought-provoking questions and enhance your understanding!
When blood pressure increases ..what pathway will the brain send signals through ?
Sympathetic pathway only
Parasympathetic pathway only
Both parasympathetic and sympathetic pathways
None of the answers are correct
Diminished perfusion could be expressed as:
Decrease in renal blood flow,decrease in glomerular filtration rate, and decrease in afferent arteriolar pressure.
Increase in renal blood flow,increase in glomerular filtration rate, and increase in afferent arteriolar pressure.
Decrease in renal blood flow,decrease in glomerular filtration rate, and decrease in efferent arteriolar pressure.
Increase in renal blood flow,increase in glomerular filtration rate, and increase in efferent arteriolar pressure.
Resistance: it is related to the length of blood vessels.
True
False
Vasomotor center (VMC) is found in:
Medulla oblongata
Temporal lobe
Midbrain
Brain stem
Mean blood pressure :
Diastolic + 0.33 (systolic-diastolic)
It calculates mean arterial pressure from measured systolic and diastolic blood pressure values
Diastolic + 33/100(systolic-diastolic)
MAP
All answers are correct
Baroreceptors are found in:
Major artries in chest
Ascending aorta
major blood vessels in chest
In arch of the aorta
Two answers are correct
Diastole: it is pressure created due to elastic of the aorta after left ventricular relaxation.
True
False
To sustain elevation of blood pressure BELOW the normal average is the :
Hypertension
Hypotension
To sustain elevation of blood pressure BEYOND the normal average is the
Hypotension
Hypertension
Systole: it is pressure created due to relaxation of left ventricle.
True
False
Choose the INCORRECT answer:
If BP decrease, we need to increase CO, SVR or both to bring it up again
If BP increases, we need to decrease CO, SVR or both to bring it back down again
If BP increases, we need to decrease cardiac output only to bring it back down again
If BP decreases, we need to increase cardiac output only to bring it up again
Two answers are incorrect

Yes it can
Definitely
Of course!

All are correct
Cells’ source of ATP is cellular respiration:
True
False
Shock is
Two answers are correct
