Answer:
Explanation:
color = pale yellow due to presence of urochrome pigment
urochrome is formed by the haemoglobin of dead RBC in liver cells
other pigment in urine - urobilin and uroerythrin
nature = acidic ph - 6
specific gravity = 1.03 - 1.04 - slightly heavier than water
smell = urine has faint aromatic odour due to bad smelling substance - urinod
quantity= daily urine output in normal adult human is 1.5 to 1.8 litres
urine output depends upon the number of factors like
1) fluid intake
2) physical activity
3) environmental temperature
4) diuretics - tea , coffee, alcohol etc
chemical composition=
water= 95-96%
urea= 2- 2.5 %
electrolyte = 2 %
uric acid = 0.3 %
creatinine - 0.3%
ammonia = 0.3%
hippuric acid = 0.3%
k + = 0.3%
h+ = 0.3%
phosphate = 0.3%
oxilates = 0.3%
