your gas exchange stations
THE ALVEOLI
Alveoli are like tiny air-filled rooms at the end of your lung corridors. Each alveolus is a delicate sac where oxygen moves into your blood and carbon dioxide moves out, making every breath count.
Exchange oxygen from inhaled air with carbon dioxide in the blood
Maintain efficient gas transfer to support metabolism and energy
Help regulate blood pH by controlling carbon dioxide levels
Work in large numbers to maximize surface area for oxygen absorption
Play a key role in overall respiratory efficiency
ALVEOLI BASICS
Common Terms + Simple Definitions
Here’s a mini glossary for alveoli related words you’ll see throughout the site:
Alveolus (singular) - Tiny air sac in the lungs where gas exchange occurs
Alveoli (plural) - The clusters of air sacs that make up the gas exchange surface of the lungs
Pulmonary Capillaries - Small blood vessels that surround alveoli for oxygen and carbon dioxide exchange
Surfactant - A substance that keeps alveoli from collapsing and allows smooth expansion
Gas Exchange - The process of oxygen entering the blood and carbon dioxide leaving
WHAT ALVEROLI WORK WITH
THE ALVEROLI + OTHER SYSTEMS
Bronchioles → Deliver air directly to alveoli
Pulmonary Capillaries → Tiny blood vessels surrounding alveoli for gas exchange
Lungs → Provide structure and support for alveoli
Diaphragm & Chest Muscles → Pump air in and out of the alveoli
Circulatory System → Carries oxygen-rich blood to the body and returns carbon dioxide to the alveoli
Nervous System → Regulates breathing to ensure proper oxygen and carbon dioxide balance
HealthY ALVEROLI…
Healthy alveoli ensure efficient oxygen delivery to your body and removal of carbon dioxide. Protecting your lungs from pollutants, smoking, and infections, along with regular deep breathing, helps maintain these vital gas exchange stations.
