Within the kidney, blood first passes through the afferent artery to the capillary formation called a glomerulus and is collected in the Bowman’s capsule, which filters the blood from its contents—primarily food and wastes. After the filtration process, the blood then returns to collect the food nutrients it needs, while the wastes pass into the collecting duct, to the renal pelvis, and to the ureter, and are then secreted out of the body via the urinary bladder.
