- Which of the following is true?a. Peripheral chemoreceptors increase firing with low arterial PO2 but are not sensitive to an increase in arterial PCO2.b. The primary stimulus to the central chemoreceptors is low arterial PO2.c. Peripheral chemoreceptors increase firing during a metabolic alkalosis.d. The increase in ventilation during exercise is due to a decrease in arterial PO2.e. Peripheral and central chemoreceptors both increase firing when arterial PCO2 increases.arrow_forwardwhen carbon dioxide travelling in the plasma reaches the alveolus and is exhaled, then what happens is that a. the volume of CO2 dissolved in the plasma would continue to drop until it reached zero b. the bicarbonate ion volume in the plasma would increase c. respiration would be stimulated and tidal volume would go up d. the CO2 attached onto the hemoglobin would release CO2 into the plasmaarrow_forwardVentilation in the capillaries is matched to perfusion. This means that a. blood pressure from capillaries must match the pressure from the arterioles b. gas pressure in the alveolar must match the pressure in the bronchioles c. ventilation is never profuse enough d. ventilation in the alveolar must match the blood flow passing over those alveiolararrow_forward
- Draw three separate oxygen-hemoglobin dissociation curves and then use arrows to show the change in oxygen saturation of most hemoglobins when: 1. deoxygenated blood enters the capillaries in the lungs. 2. oxygenated blood enters the capillaries in muscle tissue at rest. 3. oxygenated blood enters the capillaries in muscle tissue during vigorous exercise.arrow_forwardThe information provided suggests that: A. hemoglobin has more affinity to oxygen than to carbon monoxide.

While she is running, this percentage ... A. decreases because the partial pressure of O2 in her lung alveoli is reduced to below 40 mm Hg. B. decreases because the decreased PO2 in her muscles promotes O2 unloading in those tissues. C. stays the same because hemoglobin is usually 75% saturated with O2. D. increases because her muscles need more O2. E. increases because she is breathing harder.arrow_forwardDuring strenuous exercise, the oxygen-hemoglobin dissociation curve shifts to the right.
