Which of the following is the best definition for the process of internal respiration?

For the process of internal respiration to take place properly, which one of the following is TRUE about partial pressure gradients of O₂ or CO₂ before the gases reach equilibrium?

Which of the following is TRUE about ventilation-perfusion coupling at the respiratory membrane?

Name the pressure that must remain negative throughout the breathing process for normal lung function. If it does not it often leads to lung collapse.

At which portion of the hemoglobin-oxygen dissociation curve, do changes in PO2 only affect oxygen saturation of hemoglobin minimally (the relationship is horizontal in this region)?

When ventilation decreases, it causes CO₂ levels in the plasma to rise. What affect do these rising CO₂ levels have on blood pH?

Put the following events in the correct sequence for the process of inspiration.
