MDCAT · CHAPTER 13
Respiration
Follow oxygen from air to tissues, distinguish breathing from cellular respiration and calculate how depth, frequency and diffusion barriers affect exchange.
Your study notes
01 / LESSON
Build the explanation.
- Distinguish ventilation, gas exchange, transport and cellular respiration.
- Explain breathing through volume and pressure changes.
- Predict changes using ventilation and diffusion calculations.
02 / NOTES
The essentials, in one place.
- Ventilation, exchange, transport and cellular respiration are distinct and connected.
- Volume changes create the pressure differences driving airflow.
- Dead space makes breathing depth important even at equal minute ventilation.
- Area, thickness, gradients and perfusion all matter.
03 / ACTIVITY
Test the idea by changing something.
Predict the result first, run the activity, then explain what changed and why.
04 / DIAGRAM
Make the connections visible.
Air moves along pressure differences.
Gases diffuse across thin barriers.
Blood connects lungs with tissues.
Oxygen supports aerobic electron transport.
Cover the labels, redraw the sequence or comparison, and explain each connection aloud.
