Final answer:
The major waste product found in the urine of a normal individual is urea, a nitrogenous compound resulting from protein breakdown. Uric acid is also excreted in urine, which comes from nucleic acid metabolism. Both are crucial for maintaining the body's homeostasis by removing waste products through the urinary system.
Step-by-step explanation:
A major waste product found in the urine of a normal individual is urea. Urea is a nitrogen-containing molecule that is non-toxic and is formed from the breakdown of amino acids in the liver. The body then excretes it in urine, a liquid waste product of the body that is formed by the kidneys and released through the process of urination.
The normal chemical composition of urine is primarily water but also includes nitrogenous molecules such as urea, creatinine, and other metabolic waste components. Uric acid is another substantial waste product derived from nucleic acid metabolism.
Urine serves an essential role in the functions of the urinary system, maintaining homeostasis by removing waste products from blood circulation. This excretory process is critical for sustaining proper health and preventing the accumulation of harmful substances in the body.
