ANATOMY

Detailed explanation-1: -The renal circulation is unusual in that it breaks into two separate capillary beds: the glomerular bed and the peritubular bed. These two capillary networks are arranged in series, so that all of the renal blood flow passes through both.

Detailed explanation-2: -The renal vasculature also includes a third capillary bed, termed the vasa recta, which is in close alignment with the medullary renal tubules. The vasa recta emanate from the post-glomerular capillary bed and deliver oxygen and nutrients to the medullary region of the kidney.

Detailed explanation-3: -Each kidney contains approximately 500, 000 glomeruli, which are small balls of capillaries (diameter 0.1 mm) through which the blood is filtered. Glomeruli are present only in the cortex. In the healthy kidney, approximately 100 ml/min is filtered through the glomerulus and into the space outside (urinary space).

Detailed explanation-4: -Peritubular capillaries are tiny blood vessels in your kidneys. They deliver wastes to be secreted into urine (pee). They also reabsorb nutrients your body needs. Peritubular capillaries play an essential role in your urinary system.
