Gas Exchange in the Lungs

Alveoli sacs in human lung with capillaries for oxygen and carbon dioxide exchange, illustrating respiratory system microscopic anatomy and gas diffusion process

Oxygen movement from alveoli to capillaries

Gas exchange is one of the big fundamental topics of A-level biology. And it always comes down to the same three key points: 1. A large surface area of the gas exchange surface 2. A short diffusion pathway for oxygen and carbon dioxide 3. Maintenance of oxygen and carbon dioxide concentration gradients across the gas exchange surface Whether we're talking humans, fish, insects, plants.... or any organism they throw at you as an application question.... always think about how the gas exchange sys
