How will changes in arterial PO2 impact ventilation? Select the one most accurate response. Group of answer choices Small changes in arterial PO2 will result in fine changes to VE in order to maintain relatively stable arterial PO2. Arterial PO2 will not affect ventilation unless it drops below 60mmHg. O2 cannot cross the blood/brain barrier, thus cannot interact with central chemoreceptors to have an impact on ventilation. Breathing 100% O2 at atmospheric pressure will greatly reduce the urge to breathe.

Discuss the mechanisms responsible for the changes seen during incremental submaximal exercise (oxygen consumption, ventilation, blood pressure, heart rate). You will need to discuss the receptors and effectors that regulate these responses (300 words)

1a) If the ventilation/perfusion ( V/Q) ratio of a lung region decreases, how will the PO2 and PCO2 in the blood in that region change? 1b) In perfusion-limited O2 exchange, is the PO2 at the end of the pulmonary capillary closer to PA,O2 or PV,O2? 1c) Which of the following is/are higher at the base of the lung than at the apex: blood flow, V/Q, ventilation, PO2, PCO2? Please explain your answers briefly and accurately.

The ventilation/perfusion ratio: a) decreases when ventilation is increased b) increases due to dialation of the pulmonary arteries c) increases when blood flow is decreased d) is lowest at the apex of the lungs

3. Changes in government rules have caused consumers to increase their exercise, causing new demand for sneakers. At the same time, production methods have improved and allowed suppliers to make more sneakers. Draw the demand and supply curve showing the influence of these changes. What will happen to Price and Quantity as a result? _____ Price _____ Quantity

1. How are ventilation and perfusion matched in animals? What short-term changes occur to balance these two components? 2. Diagram the negative feedback loop for the homeostatic regulation of blood PO2; identify the sensors, integrators, and effectors in this system. 3. What are the critical modulators of respiration in water and air breathing animals? (i.e. what respiratory gas has primary influence on ventilation?)
