Nephrons are the functional and basic unit if excretory system
These are present in kindneys(1.3-1.8 millions)
They filter the blood and the waste excreted out as urine
The filtration is of following steps...
GLOMEULAR FILTRATION::
The blood is filtered in BOWMANS CAPSULE...due to the high pressure of different arteriole the primary urine is formed which has the same composition that of blood except the presence of RBCs
TUBULAR REABSORPTION::
Here the particular network surrounded by nephrons absorb the necessary nutrients which may go out of BOWMANSCAPSULE
TUBULAR SECRETION::
Here the PCT &DCT secretes waste to the collective tubes and also absorb the necessary nutrients
ULTRA FILTRATION::
Here the urine will be filtered and gets it amber colour due to the presence of UROCHROME pigment and only diluted urine comes out due to the presence of VASOPRESSIN hormone....
