These are the two same figures... in which you will understand about the peritubular capillariesa and bowman's gland that how they work and where they are located.
Peritubular capillaries are tiny blood vessels, in the renal system and supplied by the efferent arteriole, that travel alongside nephrons allowing reabsorption and secretion between blood and the inner lumen of the nephron. Peritubular capillaries surround the proximal and distal tubules, as well as the loop of Henle, where they are known as vasa recta.
