oedema is the accumulation of fluid in interstitial spaces

how does condition X lead to odema what force need ato change for this to occur? example of exam question

40-35mmHg arteriole end hydrostatic pressure

15-10mmHg venule end hydrostatic pressure

interstitial hydrostatic pressure values

varies by tissue (overall pretty close to 0)

think average 0mmHg

oncotic pressures in blood value = 25-28mmHg driven by albumin

oncotic P tissue = 1mmHg

net pressure arteriole end vs net pressure at venule end

(hydrostatic P blood - Hydrostatic P tissue) - (Oncotic P blood - Oncotic P tissue)
