20 Questions5 MinutesCreated by PumpingHeart24

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

True

False

Shock is

Two answers are correct
