Question

Explain about composition of urine?

Answer 1

Urine is a sterile waste product made up of water soluble products made from nitrogen.The kidneys secrete urine, a typically sterile liquid by-product of the body, through a mechanism called urination and excreted through the urethra. Urine is often used for many disease circumstances as a diagnostic function. These may b based on either physical or chemical components, that may give insight to processes within the body, often through urinalysis, a common clinical analysis of urine. Normal urine consists of water, urea, salts, and pigments.Urea is a non-toxic molecule made of carbon dioxide and toxic ammonia. Any abnormal urinary constituents are an indication of illness.Urine is an aqueous solution of greater than 95% water, with a minimum of these remaining constituents, in order of decreasing concentration:

Urea 9.3 g/L.

Chloride 1.87 g/L.

Sodium 1.17 g/L.

Potassium 0.750 g/L.

Creatinine 0.670 g/L.

Other dissolved ions, inorganic and organic compounds (proteins, hormones, metabolites).
