ANATOMY

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). Protein is only found in trace amounts compared to their values in blood plasma.

Detailed explanation-2: -Urine is about 95% water. It is not completely sterile of microorganisms, as many sources incorrectly state.

Detailed explanation-3: -3.01. 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-4: -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.
