Our friend @CPV_Physiology raises the interesting question of transport phenomena in nature. In this third post about capillary blood flow velocity I draw to your attention a nice review of the evolution of vascular systems in animals. It is a very reasonable hypothesis that the longest-lived animals have evolved an energy-efficient cardiovascular system that delivers…… Continue reading Why capillary blood flow is Slow in longer-lived species.
To continue on from yesterday’s post, Dr Ghanem replied promptly to my request for more information on his G Tube; The G tube is a tube with narrow orifice and holes in its wall built on a scale to the capillary tube. It was designed and invented by me 39 years ago. It was later…… Continue reading more on Ghanem’s Hypothesis
For nearly a decade I have been encouraging physicians to question the century-old medical school physiology shibboleth concerning fluid volume filtration from followed by absorption to the lumen of an archetypal Capillary; the filtration – absorption model. At steady state, the extended Starling principle holds that the hydrostatic capillary pressure difference declines between arteriole and…… Continue reading Starling’s Law for the Capillary-Interstitial Fluid Transfer is Wrong?
