Detailed explanation-1: -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).
Detailed explanation-2: -Urine is about 95% water. It is not completely sterile of microorganisms, as many sources incorrectly state. But it doesn’t contain any of the harmful microbes that can make you immediately sick-such as those you might ingest from contaminated wilderness water, and which are generally transferred through feces instead.
Detailed explanation-3: -Urea, together with water and other waste substances, forms the urine as it passes through the nephrons and down the renal tubules of the kidney. Two ureters. These narrow tubes carry urine from the kidneys to the bladder.
Detailed explanation-4: -Urine is composed of multiple components. Water-95%, Urea-2%, Creatinine-0.1%, Potassium-0.6%, Sodium-0.1%, Chloride-0.6%. Pigments, hormones, metabolites, and amino acids also make up a small portion of urine.
