Answer :
Final answer:
Urine is the waste material liquid formed in the kidneys, containing toxic waste substances suspended in water. The process involves filtration and reabsorption with the main waste products being urea and uric acid. The kidneys excrete nitrogenous wastes like urea from protein breakdown and uric acid from nucleic acid metabolism, along with excess water and mineral ions.
Explanation:
Urine is the waste material liquid formed in the kidneys through a process of filtration and reabsorption, containing toxic waste substances suspended in water. The kidneys remove cellular wastes like urea and uric acid from the blood to form urine, which is then excreted by the body.
The nephron, the functional unit of the kidney, filters blood to form urine by reclaiming useful materials and allowing surplus or waste molecules to flow out. The main waste products in urine are urea and uric acid, by-products of protein and nucleic acid breakdown, respectively.
The excretion of waste products by the kidneys includes nitrogenous wastes like urea from protein catabolism and uric acid from nucleic acid metabolism, along with excess water and mineral ions.
