The Correct Answer and Explanation is:

Here’s how the labels correspond to the diagram components:

1. Nose – external structure where air first enters
2. Nasal cavity – internal passageway that filters, warms, and humidifies air
3. Pharynx – shared pathway for air and food in the throat
4. Larynx – houses the vocal cords and directs air into the trachea
5. Trachea – windpipe leading downward from the larynx
6. Bronchus – large branch from the trachea entering each lung
7. Bronchioles – smaller airways branching from the bronchi
8. Respiratory bronchioles – narrowest airways leading to gas exchange units
9. Alveoli – microscopic sacs where oxygen and carbon dioxide exchange occurs
10. Right lung – contains three lobes and facilitates gas exchange
11. Left lung – contains two lobes and accommodates the heart
12. Diaphragm – dome-shaped muscle at the base of lungs that drives inhalation
13. Clavicle – collarbone positioned above the ribcage
14. Ribs – bones encasing and protecting the thoracic organs
15. Esophagus – muscular tube behind the trachea carrying food to the stomach
16. Upper Respiratory System – consists of the nose, nasal cavity, pharynx, and larynx
17. Lower Respiratory System – comprises the trachea, bronchi, bronchioles, alveoli, and lungs

The respiratory system works to deliver oxygen to the bloodstream and eliminate carbon dioxide from the body. Air enters through the nose and nasal cavity, where it’s conditioned before passing through the pharynx and larynx. The trachea directs the air into the primary bronchi, each leading to a lung. These bronchi branch into smaller bronchioles, ending in alveoli where gas exchange occurs with capillaries. The diaphragm contracts to create a pressure gradient, drawing air into the lungs. By coordinating these structures, the body maintains cellular respiration and supports life-sustaining metabolic processes.
