Renal microvasculature of the rainbow trout,Salmo gairdneri: Scanning electron microscopy of corrosion casts of glomeruli

摘要: Scanning electron microscopy of corrosion casts blood vessels permits detailed and accurate study the microcirculation. The present examined renal microvasculature rainbow trout, Salmo gairdneri. conventional picture a glomerulus with one afferent arteriole was common, but glomeruli were often supplied by two arterioles. In majority these, intrarenal artery gave rise to single that branched form smaller before reaching glomerulus. Glomeruli arterioles arose independently from also occurred. had efferent arteriole, proportion Efferent in diameter than glomerular capillaries arranged lobules, few anastomoses between so that, for or arterioles, vascular perfusion thus filtration within discrete lobules is probable.
