your airway branch

BRONCHI + BRONCHIOLIS

The bronchi and bronchioles are like the branching hallways and corridors of your respiratory building. They distribute incoming air from the trachea evenly into each lung, ensuring every part gets oxygen.

  • Carry air from the trachea into the lungs

  • Branch repeatedly to reach every area of the lungs

  • Support smooth airflow and oxygen delivery to alveoli

  • Help filter and humidify air before it reaches delicate lung tissue

  • Adjust diameter (bronchodilation/constriction) to regulate airflow

BRONCHI + BRONCHIOLIS BASICS

Common Terms + Simple Definitions

Here’s a mini glossary for bronchi + bronchiolis related words you’ll see throughout the site:

Bronchi - Large air passages that branch from the trachea into each lung

Bronchioles - Smaller branches of the bronchi that lead to alveoli

Bronchodilation - Widening of airways to allow more airflow

Bronchoconstriction - Narrowing of airways to limit airflow

Cilia - Tiny hair-like structures that move debris out of the airways

Mucus - Sticky fluid that traps dust, allergens, and pathogens

WHAT THE BRONCHI + BRONCHIOLIS WORKS WITH

the BRONCHI + BRONCHIOLIS + OTHER SYSTEMS

  1. Trachea → Receives air from the main airway

  2. Lungs & Alveoli → Deliver oxygen to and remove carbon dioxide from blood

  3. Cilia & Mucus → Trap dust and pathogens, moving them upward for clearance

  4. Smooth Muscle → Adjusts airway diameter to control airflow

  5. Nervous System → Signals bronchi/bronchioles to constrict or dilate as needed

  6. Immune System → Detects irritants and triggers protective responses like coughing

a HealthY BRONCHI + BRONCHIOLIS…

Healthy bronchi and bronchioles ensure smooth airflow, optimal oxygen delivery, and protection of delicate lung tissue. Avoiding smoke, allergens, and pollutants helps keep these airway branches clear and flexible.
