Blood pressure to Lymphatic system

Which of these does not vary directly with blood pressure?

• Total peripheral resistance

• Blood volume

• Cardiac output

• None of the above

Which of these are not a factor in regulating BP?

• Autonomic Neural Reflexes

• Cardiovascular Center

• Autonomic fibers to the heart

• Heart rate Contractility

When BP is falling, this gets stimulated to increase vasoconstriction.

• Vasomotor Center

• Cardioacceleratory center

• Baroreceptors

• Chemoreceptors

Higher brain centers may modify neutral controls of BP via?

• Median centers

• Medullary centers

• Vasomotor Center

• None of the above

Is the major factor that determines resistance.

• Vessel Length

• Vessel Size

• Vessel Diameter

• Vessel Thickness

All of these are hormones that increase BP by promoting vasoconstriction except

• Atrial natriuretic peptide

• Epinephrine and NE

• ADH

• Angiotensin II

Answer explanation

Atrial natriuretic peptide is a hormone that promotes "vasodilation" that causes decline in blood volume

Kidneys regulate blood pressure by regulating what?

• Blood volume

• Blood pressure

• Blood acidity

• Blood viscosity

I. Rising BP directly enhances filtrate formation and fluid losses

II. Falling BP causes the kidney to retain more water

Which of these are true?

• Only statement I

• Only statement II

• Both are correct

• Both are false

Chronic hypertension (High blood pressure) is persistent BP reading of?

• 140/90 or higher

• 130/90 or higher

• 120/80 or higher

• 120/90 or higher

High blood pressure is the major causes of these except?

• Myocardial infarction

• Migraine

• Stroke

• Renal disease
