okay so today I finally finished the URINARY SYSTEM.. which I hate, but now enjoy cause I totally understand everything.... This is how urine forms in the simplest term
Blood from Renal artery goes to segemental artery to interlobar artery to arcuate aretery to interlobular artery to afferent/efferent arteriole, then into the Renal Corpuscle which contains the GLomerulus and the Bowman's capsule..
in the glomerulus, blood is filtered and the filtrate containing ( plasma, ions, etc) is caught in the Bowman's capsule..
Then your filtrate is passed into the Proximal Convoluted Tubule where there is active reabsorption of nutrients, plasma proteins and ions from filtrate...
Then your filtrate becomes peritubular fluid which gies into the Loop Of Henle which function is the reabsorption of water ino the vasa recta.. Vasa recta is a capillary bed which nourishes the kidney..
Anyway after sodium and water is reabsorped into the kidney after the Loop Of Henle, the peritubular fluid goes into the Distal Convoluted Tubule which releases many toxins, drugs..
Then FINALLY the peritubular fluid becomes urine.. which is collected in the , duh, collecting tubule..
then you pee..
WAITTTTTTTTTT
not over yet...
the collecting tubule goes into the URETER which goes ALL the way to your? BLADDER..
The ureter connects to your bladder, there's 2 ureter... and ends up in a urethra.. in guys its longer than gals.. i think we all now why... then there's the internal n external sphincter... the internal opens only when you open the external.. meaning you relax yourself when you wanna pee... so thats how urine is formed..
I am so gonna ace AAP test on Friday
will YOU be my escape?
