The reasoning: filtration balanced by lymph, not by venous reabsorption
Starling–Landis equation (revised): Jv = Kf [(Pc − Pi) − σ(πp − πg)], where πg is oncotic pressure in the protein‑poor sub‑glycocalyx space, not bulk interstitium. In most steady‑state systemic capillaries the net force favours small continuous filtration along their length; lymph (~2–4 L/day in total) returns fluid and protein. Sustained venous‑end reabsorption is not the dominant steady‑state pattern (transient reabsorption occurs after an acute fall in Pc, e.g. haemorrhage — "transcapillary refill").
