This is a collection of five PowerPoints that cover some of the respiratory section of the Unit 4 Anatomy and Physiology, as below. Some have activities, others have video’s embedded so you can develop activities to in your own teaching style to aid student memory

• intercostal muscles (between each rib)
• pleural membranes

2.2 Inspiration and expiration
• role of pleural membranes
• role of diaphragm (muscle controlling breathing rate)
• role of intercostal muscles (muscle between each rib, contracts to exhale)

2.5 Respiratory malfunctions – possible causes and effects
