GENERAL HISTOLOGY

Detailed explanation-1: -Urine is an aqueous solution of greater than 95% water. Other constituents include urea, chloride, sodium, potassium, creatinine and other dissolved ions, and inorganic and organic compounds. Urea is a non-toxic molecule made of toxic ammonia and carbon dioxide.

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: -The kidney and urinary systems help the body to eliminate liquid waste called urea, and to keep chemicals, such as potassium and sodium, and water in balance. Urea is produced when foods containing protein, such as meat, poultry, and certain vegetables, are broken down in the body.

Detailed explanation-4: -Human urine is composed of water (95-96%), organic and inorganic wastes (5-4%) like urea, uric acid, creatinine, salts of phosphates and sulfates, etc. The main component of urine is water.

Detailed explanation-5: -Final answer: Urine contains nitrogenous waste in the form of urea and uric acid.
