Understanding Gas Exchange Concept Maps
A gas exchange concept map shows how oxygen enters the blood and carbon dioxide leaves it. Gas exchange happens across thin alveolar walls by diffusion, driven by concentration gradients. The map usually starts with the airways that carry air to the lungs, then moves to the alveoli, the respiratory membrane and the blood that carries gases around the body.
- Airways: trachea, bronchi and bronchioles carry air inward
- Alveoli: tiny sacs with thin walls and a large surface area
- Diffusion: oxygen and carbon dioxide move down their gradients
- Blood transport: haemoglobin carries oxygen, plasma carries carbon dioxide
Use the map to revise the pathway step by step and check where each gas moves. Generate a personalized gas exchange map from your own notes with CogniGuide.

Gas Exchange Map Questions
Answers on the biology of gas exchange and how to build your own map.
Why does oxygen move into the blood?
Oxygen is at a higher concentration in the alveoli than in the blood capillaries. It diffuses across the thin respiratory membrane down this gradient and then binds to haemoglobin in red blood cells.
What role do the alveoli play?
Alveoli provide a very large surface area and very thin walls, which speeds up diffusion of gases. Each lung contains millions of them, surrounded by a dense network of capillaries.
Which files can I use to make my map?
You can upload PDF, Word (DOCX), PowerPoint (PPTX), text, Markdown or image files, or simply type a topic such as gas exchange.
Can I turn the gas exchange map into a quiz?
Yes. The map can be turned into a quiz to test yourself, and the same notes can become flashcards. There is a free plan with 5 creations a week.
