Breathing and Exchange of Gases — Class 11 CBSE Biology revision notes
A 4-page visual revision sheet for Breathing and Exchange of Gases, written for Class 11 CBSE Biology. Formulas, diagrams and the traps that cost marks, laid out to be read the night before rather than the term before. Free, and it opens inside CapCompass.
What this Breathing and Exchange of Gases sheet covers
- Breathing vs respiration, the distinction the chapter rests on
- The respiratory tract, in order
- Alveoli, the exchange surface itself
- Mechanism of breathing, pressure does the work
- Inspiration vs expiration, one flip

- Expiration
- A quiet inspiration, volume against time
- Respiratory volumes, the numbers a spirometer reads
- Capacities, each one built by adding volumes
- vital capacity, VC
- total lung capacity, TLC
- inspiratory capacity, IC
- functional residual capacity, FRC
- Reading a spirometer trace
- Exchange of gases, simple diffusion down a gradient
- Three ways CO2 travels in blood
- Transport of oxygen
- Regulation of breathing
- Respiratory disorders
- Each disorder, one line
- Asthma
- Emphysema

- Tricks that save time
How CapCompass uses this sheet
These notes are not a standalone PDF. CapCompass plans Biology chapter by chapter against your real exam dates and free hours, and when the plan reaches Breathing and Exchange of Gases the sheet opens inside the study block itself — at the page covering the sub-topic that block is on, with the timer still running. Revision arrives at the moment the plan says revise, instead of having to be gone looking for.
