Parts of Respiratory System includes:
- External nostrils – For the intake of air.
- Nasal chamber – which is lined with hair and mucus to filter the air from dust and dirt.
- Pharynx – It is a passage behind the nasal chamber and serves as the common passageway for both air and food.
- Larynx – Known as the soundbox as it houses the vocal chords, which are paramount in the generation of sound.
- Epiglottis – It is a flap-like structure that covers the glottis and prevents the entry of food into the windpipe.
- Trachea – It is a long tube passing through the mid-thoracic cavity.
- Bronchi – The trachea divides into left and right bronchi.
- Bronchioles – Each bronchus is further divided into finer channels known as bronchioles.
- Alveoli – The bronchioles terminate in balloon-like structures known as the alveoli.

Human Respiratory System Components
The human respiratory system is essential for breathing and involves various structures that facilitate the exchange of gases. Here’s a breakdown of the options provided:
Key Components of the Respiratory System
- Larynx (i): Commonly known as the voice box, the larynx is crucial for producing sound and protecting the windpipe against food aspiration. It is part of the respiratory system.
- Nostrils (ii): The nostrils serve as the primary entry point for air into the respiratory system. They filter, warm, and humidify the air before it reaches the lungs.
- Gullet (iii): Also known as the esophagus, the gullet is not part of the respiratory system. It is responsible for transporting food from the mouth to the stomach.
- Windpipe (iv): The windpipe, or trachea, is a vital structure in the respiratory system that carries air from the larynx to the lungs.
- Lungs (v): The lungs are the main organs of the respiratory system, where gas exchange occurs. They allow oxygen to enter the blood and carbon dioxide to be expelled.
Conclusion
Based on the information above, the correct components of the human respiratory system from the options provided are:
- Larynx (i)
- Nostrils (ii)
- Windpipe (iv)
- Lungs (v)
Since the gullet (iii) is not part of the respiratory system, the correct answer is option b) which includes (i), (ii), (iv), and (v) only.
