How does this explain why a nutritionally deficient child would have edema? Starling’s Law describes how fluids move across the capillary membrane. There a WebbDescription: Ernest Starling (1866-1927) was pre-eminent in the golden age of British Physiology. His name is usually associated with his "Law of the Heart,” but his discovery of secretin (the first hormone whose mode of action was explained) and his work on capillaries were more important contributions.
WebbPhysiology. The Frank-Starling mechanism occurs as the result of the length-tension relationship observed in striated muscle, including for example skeletal muscles, arthropod muscle and cardiac (heart) muscle.
