<prompt> Which of the following oxygen-hemoglobin dissociation curves corresponds to blood during resting dark purple line and during exercise light purple line ?DABC  <response>: Factors that shift the oxygen-hemoglobin dissociation curve to the right are: CO2 released from the muscle tissue, Hconcentration in the muscle capillary blood, Temperature resulting from heat generated by the exercising muscle. The right shift of the oxygen-hemoglobin curve allows more oxygen to be released to the muscle at a given Po2 in the blood.
