how is urine produced explain the formation of urine
Answers
Heya mate, here's your answer
The first step of urine formation is ultrafiltration.
Blood passes through a network of capillaries in the kidney called the glomerulus.
It is filtered into the Bowman’s capsule (the first part of the nephron) through a fine membrane which acts like a sieve. Blood cells and proteins are too big to pass through the membrane so they remain in the blood, but everything else – water, ions, waste produce (urea) and glucose passes into the nephron.
The solution entering the nephron is called the glomerular filtrate.
The next step is selective reabsorption. It is important that waste products (urea) are excreted from the body in urine while substances your body needs – ions, water and glucose – remain in the blood so they can be used.
To achieve this, most ions and all glucose is pumped back into the blood from the nephron.
This mostly happens in the first part of the nephron, the proximal convoluted tubule.
Everything that is not pumped back into the blood moves into the bladder down the ureters as urine and is excreted.

Urine is produced under the guidance of kidneys and infrastructure of the same.
Explanation:
The urine system forms in this infrastructure- bladder, ureter, prostate gland and their blood vessels etc. are under this system.
Two spheres of the kidney remain on either side of the cutaneous vertebrae. They separate urine from blood.
This urine is collected in the urinal by gavins and from there it comes out at the will of human.
The length of the vans is 10 inches. The bladder resides in the pelvic cavity behind the sacrum and spreads in size according to the volume of urine.
In men, the length of the urinary tube is 7 inches and in women, the length of the urinary tube is 1 inch.
