ANATOMY

Detailed explanation-1: -It consists of water, urea (from amino acid metabolism), inorganic salts, creatinine, ammonia, and pigmented products of blood breakdown, one of which (urochrome) gives urine its typically yellowish colour.

Detailed explanation-2: -Human urine is composed primarily of water (95%). The rest is urea (2%), creatinine (0.1%), uric acid (0.03%), chloride, sodium, potassium, sulphate, ammonium, phosphate and other ions and molecules in lesser amounts30 (Table 1). Protein is only found in trace amounts compared to their values in blood plasma.

Detailed explanation-3: -About 91–96% of urine consists of water. The remainder can be broadly characterized into inorganic salts, urea, organic compounds, and organic ammonium salts. Urine also contains proteins, hormones, and a wide range of metabolites, varying by what is introduced into the body.

Detailed explanation-4: -Nitrogen content in urine is high, mostly in urea, which makes up more than 50 percent of the total organic acids. This includes urea from protein metabolism, sodium and potassium both of which come from food.

Detailed explanation-5: -An adult human being normally passes about 1.8 litres of urine in 24 hrs. The urine consists of 95% of water, 2.5% of urea and 2.5% other waste products.
