Which of the following statements about the human excretory system is correct?
The kidneys play a crucial role in osmoregulation and nitrogenous waste elimination.
Human excretion primarily involves the elimination of ammonia as the main nitrogenous waste.
Urine is formed in the kidneys and stored in the ureters before being excreted.
The micturition reflex is responsible for the storage of urine in the bladder.
Correct Answer
Detailed Explanation
The kidneys are essential for both osmoregulation and the removal of nitrogenous wastes, as highlighted in the NCERT context. Ammonia is not the primary waste in humans; they primarily excrete urea. Urine is stored in the bladder, not the ureters, and the micturition reflex initiates urination.
