What you practice

These are the CBSE Class 11 Breathing & Exchange of Gases skills this quiz is built around.

Explain inspiration and expiration through pressure and volume changes.
Describe alveolar diffusion using partial pressure gradients.
Interpret the oxygen dissociation curve and bicarbonate transport of carbon dioxide.

A useful tip

The oxygen-haemoglobin curve shifts right when carbon dioxide, acidity or temperature rises. That right shift unloads more oxygen exactly where active tissues need it.
