ANATOMY

Detailed explanation-1: -Urine is about 95% water and 5% waste products. Nitrogenous wastes excreted in urine include urea, creatinine, ammonia, and uric acid. Ions such as sodium, potassium, hydrogen, and calcium are also excreted. Urine produced in the kidneys travels down the ureters into the urinary bladder.

Detailed explanation-2: -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-3: -The bean-shaped kidneys filter waste products out of the bloodstream and dispose of them by creating urine. Urine is made of these waste products dissolved in water.

Detailed explanation-4: -Urea-Urea is the primary organic component in urine. It is a product of protein and amino acid metabolism. Uric Acid-Uric acid is a product of nucleic acid breakdown in the body. Creatinine-Creatinine is a product of creatine metabolism in muscles.
