CO2 content in the inspired air on being markedly increased would:

January 14, 2020 BILAL KHATTAK0

A.Increase the breathing movements
B.Decrease the breathing movements
C.Bring a state of first slow breathing followed by fast breathing

In case the concentration of oxygen in the tissues were almost as high as at the respiratory surface then:

January 13, 2020 BILAL KHATTAK0

A.Oxyhaemoglobin would dissociate to supply oxygen to tissues
B.Haemoglobin would combine with more oxygen at respiratory surface
C.Oxyhaemoglobin would not dissociate tosupply oxygen to tissues
