Your answers will be reviewed during a phone call with a course instructor.  Incorrect 0/1 Points 1. What is Starling's Law of Capillary forces? How does this explain why a nutritionally deficient child would have edema? * 1. Correct answers: Starling’s Law describes how fluids move across t he capillary membrane. There are two major opp osing forces that act to balance each other, hydr ostatic pressure (pushing water out of the capilla ries) and osmotic pressure (including oncontic pr essure, which pushes fluid into the capillaries). Bo th electrolytes and proteins (oncontic pressure) i n the blood affect osmotic pressure, high electrol yte and protein concentrations in the blood woul d cause water to leave the cells and interstitial sp ace and enter the blood stream to dilute the hig h concentrations. On, the other hand, low electro lyte and protein concentrations (as seen in a nutr itionally deficient child) would cause water to lea ve the capillaries and enter the cells and interstiti al fluid which can lead to edema.
