Which of the following is not associated with the process of respiration?
Correct answer: C. Bladder
- A. Lungs
- B. Gills
- C. Bladder
- D. Trachea
Explanation
The bladder is not directly associated with the process of respiration. The bladder is an organ found in the urinary system of vertebrates, including humans. Its primary function is to store urine temporarily until it is expelled from the body during the process of urination. Urine is produced in the kidneys as a waste product of metabolism and has no direct involvement in the respiration process.

About Respiration
The human respiratory system includes the air passages, lungs, alveoli and breathing muscles, while gaseous exchange explains how oxygen enters blood and carbon dioxide leaves it by diffusion. The effects of smoking include damage to cilia and alveoli, reduced gas exchange, chronic bronchitis, emphysema and increased risk of lung cancer.
