Question

Describe in detail the three processes that the nephrons of the kidneys use to produce urine.

Answer 1

kidney is made up of about a million filtering units called nephrons.each nephron includes a filter,called the glomerulus,and a tubule.

the nephrons work through a 2 step process

1. the glomerulus filters your blood
2. and tubule returns needed substances to your blood and removes wastes.

the glomerules filters your blood

as blood flows into each nephron,it enters a cluster of tiny blood vessels-the glomerulus.the thin walls of the glomerulus allow smaller molecules,wastes,and fluid-mostly water-to pass into the tubule.larger molecules,such as proteins and blood cells,stay in the blood vessel.

the tubule returns needed substances to your blood and removes wastes

a blood vessel runs alongside the tubule.as the filtered fluid moves along the tubule,the blood vessel reabsorbs almost all of the water,along with minerals and nutrients your body needs.the remaining fluid and wastes in the tubule become urine.

urine is formed in the kidneys through a filtration of blood.blood flows into our kidney through renal artery.this large blood vessel branches into smaller and smaller blood vessels until the blood reaches the nephrons.in the nephron,the blood is filtered by tiny blood vessels of the glomeruli and then flows out of your kidney through the renel vein.
