PROCESS
A.Formation
In theKidney
– The nephrons filter out water, wastes and other substances like urea and salts from the blood.
– Followed by the reabsorption by the kidney of water and other essential substances like amino acids and glucose.
– The chemicals actively removed (urea,salt,etc.) from the blood and the filtrate not reabsorbed from the urine.
B. General Process
– Urine formed in the kidney passes into a long, narrow tube called ureter.
– Ureter from each kidney connects to the urinary bladder, a sac of smooth muscles that can hold 400 to 500 mL of urine.
– When the urinary bladder is full, it contacts and forces the urine throughout the urethra.
– The process of expelling urine is called urination.
