WebTo examine the relationship between APR and net interstitial pressure, we measured peritubular capillary hydrostatic and oncotic pressure, single nephron filtration rate, APR, absolute distal reabsorption (ADR), and tubular hydrostatic pressure in hydropenic, saline-loaded, and plasma-loaded rats. WebPeritubular capillaries are downstream of the efferent arterioles. Efferent arterioles constrict to maintain a high upstream pressure in the glomerulus to promote filtration (maintain …
WebThe total oncotic pressure present at the venous end could be considered as +25 mmHg. [citation needed] In the beginning (arteriolar end) of a capillary, there is a net driving force ( ) outwards from the capillary of +9 mmHg. In the end (venular end), on the other hand, there is a net driving force of −8 mmHg. [citation needed] WebPeritubular capillary oncotic pressure c. Interstitial hydrostatic pressured. Interstitial osmotic pressure e. Peritubular capillary osmotic pressure ANS: B, E The osmotic force generated by active sodium transport promotes the passive diffusion of water out of the tubular lumen and into the peritubular capillaries.
WebThe blood perfusing the peritubular capillaries then would have increased oncotic pressure because a greater fraction of protein-free ultrafiltrate would concentrate the remaining proteins more. This effect is not linear, so that the oncotic pressure would increase more than the concentration.

The opposing … taps schedule saThroughout the body, dissolved compounds have an osmotic pressure. Because large plasma proteins cannot easily cross through the capillary walls, their effect on the osmotic pressure of the capillary interiors will, to some extent, balance out the tendency for fluid to leak out of the capillaries. In other words, the oncotic pressure tends to pull fluid into the capillaries. In conditions where plasma proteins are reduced, e.g. from being lost in the urine (proteinuria), ther… taps schedulingWebWhat feature of peritubular capillaries, compared to that of glomerular capillaries, ensures water reabsorption?
