WHAT IS STARLING'S LAW OF CAPILLARY FORCES?
HOW DOES THIS EXPLAIN WHY A NUTRITIONALLY DEFICIENT CHILD WOULD HAVE EDEMA?
- STARLING'S LAW DESCRIBES HOW FLUIDS MOVE ACROSS THE CAPILLARY
MEMBRANE. THERE ARE TWO MAJOR OPPOSING FORCES THAT ACT TO BALANCE EACH OTHER,
HYDROSTATIC PRESSURE (PUSHING WATER OUT OF THE CAPILLARIES) AND OSMOTIC PRESSURE
(INCLUDING ONCONTIC PRESSURE, WHICH PUSHES FLUID INTO THE CAPILLARIES).
BOTH ELECTROLYTES AND PROTEINS (ONCONTIC PRESSURE) IN THE BLOOD AFFECT
OSMOTIC PRESSURE, HIGH ELECTROLYTE AND PROTEIN CONCENTRATIONS IN THE BLOOD
WOULD CAUSE WATER TO LEAVE THE CELLS AND INTERSTITIAL SPACE AND ENTER THE BLOOD
STREAM TO DILUTE THE HIGH CONCENTRATIONS.
, ON, THE OTHER HAND, LOW ELECTROLYTE AND PROTEIN CONCENTRATIONS (AS SEEN IN
A NUTRITIONALLY
DEFICIENT CHILD) WOULD CAUSE WATER TO LEAVE THE CAPILLARIES AND ENTER THE CELLS
AND INTERSTITIAL

FLUID WHICH CAN LEAD TO EDEMA.
HOW DOES THE RAAS (RENIN-ANGIOTENSIN-ALDOSTERONE SYSTEM) RESULT IN
INCREASED BLOOD VOLUME AND
INCREASED BLOOD PRESSURE?
WGU D236 PATHOPHYSIOLOGY OA EXAM STUDY GUIDE 2023 QUESTIONS AND ANSWERS
- A DROP IN BLOOD PRESSURE IS SENSED BY THE KIDNEYS BY LOW PERFUSION, WHICH IN
TURN
,BEGINS TO SECRETE RENIN.
RENIN THEN TRIGGERS THE LIVER TO PRODUCE ANGIOTENSINOGEN, WHICH IS CONVERTED TO
ANGIOTENSIN I
IN THE LUNGS AND THEN ANGIOTENSIN II BY THE ENZYME
ANGIOTENSIN-CONVERTING ENZYME (ACE). ANGIOTENSIN II STIMULATES PERIPHERAL
ARTERIAL
VASOCONSTRICTION WHICH RAISES BP.
, ANGIOTENSIN II IS ALSO STIMULATING THE ADRENAL GLAND TO RELEASE ALDOSTERONE,
WHICH ACTS TO
INCREASE SODIUM AND WATER REABSORPTION INCREASING BLOOD VOLUME, WHILE ALSO
INCREASED
POTASSIUM SECRETION IN URINE.
HOW CAN HYPERKALEMIA LEAD TO CARDIAC ARREST?
- NORMAL LEVELS OF POTASSIUM ARE BETWEEN 3.5 AND 5.2 MEQ/DL.
HYPERKALEMIA REFERS TO POTASSIUM LEVELS HIGHER THAT 5.2 MEQ/DL.
