William Starling

William Starling was a physiologist best known for discovering the "Starling Law" of the heart, which explains how the strength of heart contractions is directly related to the volume of blood filling the heart before it beats. This means that the more blood (preload) that fills the heart, the more forcefully it contracts, helping to balance the output of blood from the heart and maintain efficient circulation. His work was fundamental in understanding cardiac function and has influenced medicine and physiology by showing how the heart adapts to varying blood volumes.
