Following are the statements about transport of respiratory gases in rabbit I. Percentage of saturation of haemoglobin occurs more under low temperature and CO2 which cause shifting of oxygen dissociation curve towards y-axis II. In systemic arteries Po2 is about 95 mm Hg so 97% Hb is saturated in them III. CO2 is transported in the form of carbamino compounds through plasma only IV.
