ANATOMY

Detailed explanation-1: -In general, urine is composed of approximately 95% water and 5% waste products, metabolites, proteins, inorganic ions (e.g., sodium, potassium) and other organic molecules (urea, uric acid, carbohydrates). It is a more dilute proteome and metabolome than blood.

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: -Urine is about 95% water. It is not completely sterile of microorganisms, as many sources incorrectly state.

Detailed explanation-4: -Urine is composed of 95% water approximately, and the rest 5% is composed of solutes, such as, sodium, urea, potassium, chloride, and creatinine.

Detailed explanation-5: -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.
