Question

The diagram shows organs of the human excretory system labelled as A, B, C and D. Identify the label of the organ through which urine leaves the urinary bladder.

• A. A
• B. B
• C. C
• D. D

Answer 1

The correct option is D D

The organ labelled A is the kidney. From the kidney, the urine moves into the ureter, labelled as B in the figure. Through the ureters, the urine is collected in the urinary bladder. The urinary bladder, labelled C, is the organ for the temporary storage of urine. The urethra, labelled D, is the duct, that carries urine from the urinary bladder to the outside.

So, the correct answer is option D.
