Pathway of Air in the Human Body

When we breathe, air follows this path:

1. Nose/Nasal Cavity – Air enters, gets filtered, warmed, and moistened.
2. Pharynx (Throat) – A passage for both air and food.
3. Larynx (Voice Box) – Directs air and prevents food from entering the windpipe.
4. Trachea (Windpipe) – A tube that carries air to the lungs.
5. Bronchi – Trachea splits into two tubes, one for each lung.
6. Bronchioles – Smaller branches inside the lungs.
7. Alveoli (Air Sacs) – Tiny sacs where oxygen enters the blood and carbon dioxide is removed.

This cycle repeats with every breath, helping us get oxygen and remove carbon dioxide.
