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 membr ... ane. 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? - ANSWER A drop in blood pressure is sensed by the kidneys by low perfusion, which in turn begins to secrete renin.
