High hydrostatic pressure in capillaries forces fluid out to form tissue fluid; as hydrostatic pressure decreases and plasma protein concentration increases along the capillary bed, water re-enters capillaries by osmosis at the venule end.
A pressão hidrostática elevada nos capilares força o fluido para fora para formar o fluido tecidual; à medida que a pressão hidrostática diminui e a concentração de proteínas plasmáticas aumenta ao longo do leito capilar, a água reentra nos capilares por osmose na extremidade venular.
| Front | What are the steps for formation of tissue fluid |
|---|---|
| Back | Hydrostatic pressure in capillary greater than hydrostatic pressure in tissue fluid. There is an overall outward force causing fluid to be forced out of capillary forming tissue fluid Hydrostatic pressure in capillary reduces in capillaries therefore hydrostatic pressure at venule end of capillary bed is lower. Due to fluid loss and increasing plasma protein concentration the water potential at venule end of capillary bed is lower than the water potential in the tissue fluid Water re-enters the capillaries from the tissue fluid at the venule end by osmosis |
