Questions: Examine and interpret the graph regarding the effects of temperature on oxyhemoglobin dissociation by clicking the box(es) that apply. Effect of temperature Check All That Apply As body temperature increases, the percent saturation of hemoglobin decreases. As body temperature decreases, there is a "shift right" in the oxygen dissociation curve. When a person is exercising, there is a "shift left" in the oxygen dissociation curve. When a person is exercising, percent saturation of hemoglobin increases. When a person has hypothermia, percent saturation of hemoglobin increases. At a person's normal body temperature, there is more oxygen bound to hemoglobin compared to at higher body temperature.

1. As body temperature increases, the percent saturation of hemoglobin decreases.

   • This statement is true based on the oxyhemoglobin dissociation curve, where higher temperatures lead to a decrease in hemoglobin saturation.

2. As body temperature decreases, there is a "shift right" in the oxygen dissociation curve.

   • This statement is incorrect. A decrease in body temperature would actually cause a "shift left" in the oxygen dissociation curve, indicating increased hemoglobin affinity for oxygen.

3. When a person is exercising, there is a "shift left" in the oxygen dissociation curve.

   • This statement is correct. During exercise, there is an increased demand for oxygen, leading to a "shift left" in the curve to facilitate oxygen release to tissues.

In summary, as body temperature increases, the percent saturation of hemoglobin decreases. A decrease in body temperature causes a "shift left" in the oxygen dissociation curve. During exercise, there is a "shift left" in the oxygen dissociation curve to enhance oxygen delivery to tissues.
