Hey

Here is your answer,

The kidney if full of thousands of nephrons that carry filtrate from the glomerulus/bowmans capsule through the interstitial fluid where secretion and reasbsorbtion occurs so that urine becomes more dilute or concentrated depending on quite a few things such as salt concentration, water consumption, Anti diuretic hormone concentration, and other factors.

Basically no nephrons = no excretion
