Urine composition varies from time
to time and reflects the amounts of
water and solutes that the kidneys
eliminate to maintain homeostasis.
 Normal urine is 95% water, and also
contains urea, uric acid, a trace of
amino acids, and electrolytes.

Urine Elimination

After forming in the nephrons, urine passes
from the collecting ducts to the renal
papillae, then to the minor and major
calyces, and out the renal pelvis to the
ureters, urinary bladder, and finally to the
urethra, which conveys urine to the outside
