3 important questions on Physiology of Exercise - metabolic-cardiovascular-ventilaory coupling - Ventilatory coupling to metabolism
What is the physiologic dead space?
The difference between the total ventilation and the air that actually participates in gas exchange. This difference depends on the air in the air tracts that don't participate in gas exchange and underperfused alveoli (= alveoli that don't receive enough blood or air to exchange to it's full potential)
What happens with Ve when the VD/VT ratio increases? Explain.
Ve increases also. Because there is more air needed that can participate in gas exchange to eliminate the same amount of CO2.
Why takes the acid-base balance more time to recover after heavy or very heavy exercise, compared to moderate intensity exercise?
pH recovery in this stage is linked to the rate of regeneration of HCO3 - . And this is linked to the catabolism of lactate fig. 2.47.
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
Remember faster, study better. Scientifically proven.
