THE LUNGS

The lungs are like the main air-filled rooms in your respiratory building. They take in oxygen from the air and remove carbon dioxide, keeping every cell in your body supplied with the oxygen it needs to function.

  • Absorb oxygen from inhaled air into the bloodstream

  • Remove carbon dioxide from the blood during exhalation

  • Support energy production and overall metabolism

  • Help maintain blood pH balance

  • Work with the diaphragm and chest muscles to control breathing

LUNG BASICS

Common Terms + Simple Definitions

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

Lungs - Main respiratory organs where oxygen enters and carbon dioxide leaves the blood

Right Lung - Larger lung with three lobes

Left Lung - Smaller lung with two lobes to accommodate the heart

Pleura - Protective membranes surrounding the lungs

Respiration - The process of inhaling oxygen and exhaling carbon dioxide

Cilia & Mucus - Work together to trap and remove particles from the lungs

WHAT THE LUNGS WORK WITH

THE LUNGS + OTHER SYSTEMS

  1. Bronchi & Bronchioles → Distribute incoming air evenly throughout the lungs

  2. Alveoli → Sites of gas exchange between air and blood

  3. Diaphragm & Intercostal Muscles → Pump air in and out of the lungs

  4. Circulatory System → Carries oxygen to tissues and returns carbon dioxide to the lungs

  5. Nervous System → Regulates breathing rate and reflexes like coughing

  6. Immune System → Defends lungs from pathogens and inhaled irritants

HealthY LUNGS…

Healthy lungs efficiently exchange gases, protect against infections, and support energy production. Avoiding smoke, pollutants, and infections, along with regular movement and deep breathing, keeps your lungs strong and functional.
