!Urinary System

!!Overview

The urinary system influences the organism's homeostasis by osmoregulation. It's functions are:

1. __filtration__ of the ((Circulatory - Blood|blood)) — in the ((Urinary - Kidneys - Parenchyma|kidneys' cortex)), blood plasma is filtered from the glomeruli into the glomerular capsule and flows down the tubular system in the ((Urinary - Kidneys - Collecting Tubules|medulla portion)) of the kidney.

2. __reabsorption__ — a major part of the primary urine is returned to ((Circulatory - Veins|blood vessels)) that surround the ((Urinary - Kidneys - Collecting Tubules|tubules)) of the medullary region.

3. __secretion__ — the remaining liquid becomes urine, which travels down collecting ducts to the ((Urinary tract - Mucosa (Urothelium)|renal pelvis)).

4. __excretion__ — the urine is stored in the ((Urinary - Bladder - Trigon Mucosa|urinary bladder)) and is expelled via the ((Urinary tract - Mucosa (Urothelium)|urethra)), controlled by ((Urinary - Bladder muscle and Sphincters|sphincter muscle))s.
