Verified step by step guidance

Understand that nitrogenous waste products are substances that contain nitrogen and are typically excreted by the kidneys.

Recognize that the primary nitrogenous waste products in the human body are urea and creatinine.

Urea is produced in the liver from ammonia, a toxic byproduct of protein metabolism, and is then transported to the kidneys for excretion.

Creatinine is a waste product formed from the normal breakdown of muscle tissue and is also excreted by the kidneys.

Other substances listed, such as glucose, ketones, lactic acid, carbon dioxide, bilirubin, and cholesterol, are not primarily nitrogenous waste products.
