Question at position 1 The urinary system excretes carbon-containing wastes from the body.TrueFalse

BlackTom AI · Accepted Answer

Question restatement: The prompt asks whether the statement 'The urinary system excretes carbon-containing wastes from the body' is True or False.
Option 1: True. This is not accurate because the primary role of the urinary system is to remove nitrogenous wastes (like urea), excess water, and salts from the bloodstream, not carbon-containing wastes. While some carbon compounds are eliminated indirectly, the main carbon-containing outputs are managed elsewhere, such as CO2 expelled by the lungs.
Option 2: False. This is the correct characterization: carbon-containing wastes are largely handled by other systems, especially the respiratory system, which excretes carbon dioxide as a waste product of metabolism. The kidneys’ main job is to filter blood to remove metabolic products like urea, creatinine, and excess electrolytes, not to eliminate most carbon-containing wastes.
Why the other choice is misleading: Saying the urinary system excretes carbon-containing wastes conflates different waste streams and overlooks the distinct physiological pathways for carbon-containing waste (notably CO2 vs. water-soluble carbon-containing compounds). It also ignores that CO2 is primarily expelled via the lungs, not via urine, which is a common point of confusion in introductory biology.
In summary, the statement mismatches the primary waste-removal systems, and the correct understanding is that the urinary system handles nitrogenous wastes and solutes, while carbon-containing wastes are mainly exhaled through respiration.
