All the following are true regarding blood supply to the kidney, except -

Kidney has five independent vascular segments Segmental arteries divide into lobar branches. Area of kidney supplied by lobar artery → renal → includes 1-2 pyramids and the adjacent part of the cortex. Branches of renal arteries are end arteries. Renal blood passes through 2 sets of capillary plexus. High-pressure bed (60 mmHg) of glomerular plexus for filtration. Low-pressure bed (13mmHg) of peritubular plexus for selective reabsorption and nutrition. These are connected by efferent glomerular arterioles which act as a renal portal system.
