0 Time/min 39 G AS E XCHANGE (2) The amount of air breathed in/out per minute is the pulmonary ventilation. Pulmonary ventilation = tidal volume (volume per breath) × rate of breathing Gas exchange in the alveoli In the alveoli, oxygen and carbon dioxide diffuse in opposite directions down concentration gradients. These gradients are maintained by: ● circulation of blood – as blood around an alveolus becomes more oxygenated, it is moved on and replaced by deoxygenated blood; ● ventilation – as the air in the alveolus loses oxygen (and gains CO2), it is replaced with air high in oxygen and low in CO2.

Inspiration starts, stimulating stretch receptors in the thorax wall. 2 Stretch receptors send inhibitory impulses to the inspiratory centre, reducing the number of impulses to the intercostal muscles and diaphragm. 4 Expiration occurs passively. Stretch receptors send fewer and fewer inhibitory impulses: at the end of expiration, inhibition of the inspiratory centre is removed. 3 Inhibition of the inspiratory centre increases as inspiration gets deeper. Eventually, no impulses are sent to the intercostal muscles and diaphragm and further inspiration is prevented.
