انسانی گردشی نظام میں، کیپلیریوں سے بافتوں کے سیال میں مواد کی منتقلی کا کیا سبب ہے؟
Explanation
The primary force driving the transfer of materials from capillaries to tissue fluid is blood pressure.
This pressure pushes fluid and solutes out of the capillaries at the arterial end,
Where it is higher, and draws fluid back in at the venous end, where it is lower.
This process is called filtration.
