(c) Outer part of kidney (cortex) is contains malpighian
corpuscle, PCT and DCT .

(c) A person feel the sensation of micturation when the
quantity of urine in the bladder is about 300cc., The
average capacity of urinary bladder is 700- 800 ml.

and if the person is starving, he will have less urea in
his urine.
