Starling's forces

Starling's forces describe how fluid moves between blood vessels and surrounding tissues. They depend on two main factors: the blood's pressure within the vessels (which pushes fluid out) and the osmotic pressure created by plasma proteins (which pulls fluid back in). The balance between these forces determines whether fluid leaks into tissues or is drawn back into the bloodstream. When these forces are in harmony, fluid exchange maintains healthy tissue function. Imbalances can lead to swelling or fluid retention, as seen in conditions like edema.
