BREATHING & LUNG VOLUME

Slide 11 - Tekstslide

TASK. Copy & finish the text. 
When you inhale the diaphragm muscle
contracts / relaxes . This pulls the diaphragm upwards / downwards . The intercostals relax / contract and pull the ribcage upwards / downwards . This increases / decreases the volume inside your rib cage. The air now rushes into / out of the lungs. This happens because the air pressure in the lungs is lower / higher than the air pressure outside the body.
