How do these clinical findings relate to the internal respiration in Cari’s body?

Which of the symptoms Cari has described are due to lack of oxygen and reduced oxygen exchange at her tissues? Cari’s symptom of “panting like a dog”, not be able to catch her breath, and c/o chest pain are due to the lack of oxygen and reduces in oxygen exchange at her tissues. J.) As Cari’s Pco2 and alkaline blood pH rose, how was the oxygen-carrying capacity of hemoglobin affected? As Pco2 rises, hemoglobin releases O2 more readily. Thus, an increased Pco2 produces a more acidic environment, which helps release O2 from hemoglobin. K.) How would you have expected Cari’s decreased Pco2 and alkaline blood pH to have affected her breathing? As acidity increases (pH decreases), it enhances the unloading of oxygen from hemoglobin. L.) How would administration of oxygen enhance Cari’s central drive to breathe? M.) Which anatomical structures in Cari’s respiratory systems were initially involved? Nasal passages, lungs, and larynx N.) Why was Cari plagued with a chronic smoker’s cough? Because the mucus had thickened
