Nephrons
Nephrons are the basic structural
and functional units of the kidneys. Each
of the kidneys contains over a million nephrons. Nephrons function by filtering
blood and then removing needed substances from the filtrate before eliminating
the remaining fluid that contains water, metabolic waste, and toxins.as urine. This process occurs through three stages which
are ultrafiltration, selective reabsorption and osmoregulation.
Zone 3 is a tropical zone, while zones 2 and 4 are temperate.
Since Zone 3 is around the equator and between the two tropics, it is a tropical zone.
Zone 2 and 4 are temperate since they are farther away from the equator, but not too close to the North and South poles.
I hope this helped! :-)
