Document Summary

Interlobar arteries (up renal columns, between pyramids) Leads to a ball of capillaries = glomerulus. In cortex, peritubular capillaries branch off of the efferent arterioles supplying the tissue near the glomerulus, the proximal and distal convoluted tubules. In the medulla, the efferent arterioles give rise to the vasa recta, supplying the nephron loop fig. Renal tubule: long, coiled tube that converts the filtrate into urine. Consists of the glomerulus and a 2- layered glomerular capsule that encloses glomerulus. Parietal (outer) layer is simple squamous epithelium. Visceral (inner) layer consists of cells called podocytes that wrap around the. Capsular space separates the two layers of glomerular capsule glomerular capillaries of the glomerulus filtrate collects in capsular space, flows into proximal convoluted tubule. Duct leading away from the glomerular capsule and ending at the tip of the medullary pyramid. Active transport of salts and have many mitochondria. Begins shortly after the ascending limb re-enters the cortex.
