Description

Restricting the airway produced changes in the rate and depth of breathing.

Can you explain why in a restricted airway the depth and rate of breathing increases? Your answer should include a discussion on factors that affect ventilation and gas exchange as well as central and peripheral chemoreceptors (8 marks)

Part 1: What does the restriction of an airway mean in relation to the flow of air. How does breathing rate and depth change in restricted airway. Refer to data.

Over time what physiological changes does this lead to (consider gases and pH in blood and detection).

Part 2: What are the factors that affect ventilation and gas exchange. Explain the feedback mechanism involved in the brain and the control over relevant muscle groups and how their behaviour changes. How do these compensatory mechanisms affect breathing pattern. Note the marks for this question which indicates more in depth explanations are needed compared to the shorter answers
