9. It is a characteristic of urine

that could provide health

information.

A. ph B. Color C. Smell

URINE a watery, typically

yellowish fluid stored in the

bladder and discharged

through the urethra. It is one

of the body's chief means of

eliminating excess water and

salt, and also contains

nitrogen compounds such as

urea and other waste

 SMELL

The smell of urine may provide

health information.

 Urine smell indicates age of

the urine and may indicate the

prescence of glucose and

ketones.

 The pH of normal urine is

generally in the range 4.6 – 8,

with a typical average being

around 6.0.

DENSITY

Density is also known as

“specific gravity.” This is the

ratio of the weight of a

volume of a substance

compared with the weight of

the same volume of distilled

water. The density of normal

urine ranges from 0.001 to

Urine is composed of 95%

water. This may fluctuate

depending on the person’s

intake of fluids. The other

percent consists of chemicals

that breakdown in

water. Approximately 50 to 60

gram of dissolved solid

material is excreted daily in

URIC ACID

Uric acid is a chemical that’s

produced when your body

breaks down purines. They’re

also created during the

digestion of certain foods,

such as Sardines, Mushrooms,

Mackerel, Peas and Liver. The

average daily excretion of uric

acid is about 0.7 g, but an

CREATININE AND

CREATINE

Creatine is part of the cycle

that produces energy needed

to contract muscles.

Creatinine is a waste product

produced by muscles from the

breakdown of a compound

called creatine. It is removed

from the body by the kidneys,

PHOSPHATE

Phosphate is a charged particle

(ion) that contains

the mineral phosphorus.

Phosphates. The amount of

phosphates present in the urine

also depends upon the diet; the

amount is higher when the diet

contains food high in

phosphorus.

OXALATE

Oxalate is a natural end

product of metabolism in the

body.

The excretion of oxalate is

increased by ingestion of

fruits and vegetables contain

ing high oxalates (spinach).

POTASSIUM

Potassium is also an electrolyte.

Our body uses what it needs, and

the kidneys put the rest into
