nephrons
Blood carries waste products to the kidney when it is filtered out forming urine.
the renal medulla contains capillaries and urine forming tubules
The microscopic, functional unit of the kidney and the site of urine-production is the Nephron.
kidney
Ureter
The kidney filters waste products out of the blood, ultimately forming urine.
removal of kidney stones or incision to remove a renal calculus
In fact, the kidney dose not receives the urine but it produces the urine by receiving the filtrate from the blood vessels . and the first part wich receives the filtrate is the " glomerus"
juxtaglomerular apparatus
This unit is called the nephron.nephronnephronsglomerulus/ glomeruli and associated nephronsnephrons
Urine goes to the collecting duct then to the Renal Pelvis. Each kidney has one Ureter that carries Urine to the bladder. The urine from the kidneys flows down the ureters into the bladder and is then passed out of the body through the urethra.
it's a simple answer: the kidney (and a simple answerer : its the bladder)
