Pulmonary Ventilation arrow Alveolar Diffusion arrow Gas Transport arrow Tissue Diffusion arrow Cellular Respiration
Core Logic
The correct physiological sequence of respiration in humans is:
- Pulmonary ventilation (breathing) (C)
- Diffusion of gases (O₂ and CO₂) across alveolar membrane (B)
- Transport of gases by blood (E)
- Diffusion of O₂ and CO₂ between blood and tissues (A)
- Utilisation of O₂ by cells for catabolic reactions / cellular respiration (D)
Step 1: Result
The correct sequential order is C arrow B arrow E arrow A arrow D.
Pattern Recognition
Sees: "respiration steps order". Shortcut: Starts with Pulmonary ventilation (C) and ends with Cellular respiration (D).
