Explanation:
Detailed explanation-1: -Physiologically, uric acid is freely filtered by glomerulus; along the proximal tubule it is reabsorbed and secreted, with a fractional excretion equal to 6-12%. During the last decades many efforts have led to a better understanding of the molecular basis of renal urate handling.
Detailed explanation-2: -Urea is produced when foods containing protein, such as meat, poultry, and certain vegetables, are broken down in the body. Urea is carried in the bloodstream to the kidneys, where it is removed along with water and other wastes in the form of urine.
