During exercise, the cardiovascular system must supply muscles with large amounts of oxygen and fuel and get rid of a lot of wastes. How do the cardiovascular systems of athletes respond to prolonged exercise? During athletic training, the oxygen–hemoglobin dissociation curve a. shifts to the right, unloading more oxygen to tissues. b. shifts to the right, unloading less oxygen to tissues. c. shifts to the left, unloading more oxygen to tissues. d. shifts to the left, unloading less oxygen to tissues.

Hello, everyone here We have a question that says the board effect helps blank oxygen into the tissues because of the blank partial pressure of carbon dioxide in the metabolically active tissues. The Bohr effect describes hemoglobin, is lower affinity for oxygen, secondary to increases in the partial pressure of carbon dioxide and or decreased blood ph. This lower affinity increases the unloading of oxygen into tissues to meet the oxygen demand. So our answer is a unload and high. The Bohr effect helps unload oxygen into the tissues because of the high partial pressure of carbon dioxide and the metabolically active tissues. Thank you for watching. Bye!
