10 Questions
What factor assists in the non-hormonal control of blood volume by kidneys and leads to an increase in urinary output with an increase in arterial pressure?
Sympathetic impulses to kidney
Which mechanism involves slow, long-lasting changes in blood volume and is also known as Pressure Diuresis & Natriuresis?
Rennin angiotensin mechanism
Which hormone is involved in long-term regulation of arterial blood pressure and leads to an increase in blood pressure by vasoconstriction?
Angiotensin II
Which reflex is involved in short-term regulation of arterial blood pressure and is activated by changes in atrial and pulmonary pressures?
Bainbridge reflex
Which factor maintains blood pressure for days, weeks, months, or even years by controlling renal body fluid pressure systems?
Involves kidney and body fluids
What is the effect of a decrease in blood pressure (BP) on urinary water and Na+ excretion?
Urinary water and Na+ excretion decrease
Which mechanism leads to an increase in arterial BP and subsequent increase in urinary Na+?
Pressure Natriuresis
What is the effect of sympathetic impulses to the kidney when BP falls below normal?
Renal vasoconstriction and salt and water retention
What is the basis of giving diuretics in hypertensive patients?
To increase urinary output and decrease BP
What is the effect of aldosterone when BP falls below normal?
Decrease in urinary output and increase in BP
Test your knowledge of the mechanisms involved in regulating arterial blood pressure, including capillary fluid shift, stress relaxation, baroreceptor reflex, hormonal regulation, and long-term regulation involving the kidneys and body fluids.
