LUNG VOLUMES AND CONTROL OF BREATHING

1. DEFINE LUNG VOLUMES... 2. dESCRIBE 2X METHODS OF BREATHING CONTROL... 3. cREATE REVISION RESOURCES FOR LUNG VOLUMES AND BREATHING CONTROL...

Objectives:

QUICK FIRE RECAP! 1-11? !NO NOTES!

STARTER:

Describe the process of inspiration. (4marks) -*without your notes!

IN PAIRS: Research Activity: Find and define each of the 6x terms on the graph... *Summarise in your own words!

LUNG VOLUMES

Putting it all together - - - - -> Questions: 1. Inspiratory Reserve Volume is approx. ??? 2. Expiratory Reserve Volume is approx. ??? 3. Total Lung Capacity is approx. ???

lung volumes:

LUNG VOLUMES - Colour Version

Fold your paper into 8 squares! Rip - carefully!

Create Flashcards! Think-Pair-Share! Lung Volume on 1x side... Definition on the other... Turn them over... Test each other on memory recall!

ACTIVITY 2EXAM STYLE QUESTIONS!

NEURAL CONTROL 1. Medulla Oblongata in the brain... Neurones - cells conduct nerve impulses which are part of the brain stem... 2. Dorsal Respiratory Group (DRG)... 3. Ventral Respiratory Group (VRG)... 4. DRG and VRG cause the intercostal muscles to contract harder to increase breathing rate (inspiration and expiration)...

CONTROL OF BREATHING

CHEMICAL CONTROL 1. Chemoreceptors pick up chemical changes... Oxygen (02), Carbon Dioxide (CO2) and Hydrogen Ions (H+)... 2. Found in the aortic arch and carotid artery... Detect blood acidity levels... 3. Send signals to the Medulla that will change breathing rate...

CONTROL OF BREATHING

flowcharts:control of breathing

Create 2x flowcharts for control of breathing - 1x NEURAL and 1x CHEMICAL.

Create a knowledge organiser - respiratory system topics we've covered! - Structure(upper & lower tract) - Function(inspiration, expiration & gaseous exchange) - Lung volumes - Control of Breathing(chemical & neural)
