What is Starling's Law of Capillary forces?
How does this explain why a nutritionally deficient child would have
edema? - ANSWER- 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.
