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