WitrynaOxygen transport by blood is also influenced by the oxygen affinity of hemoglobin, as defined by the shape and position of the oxygen-hemoglobin dissociation curve. An important feature of the oxygen-hemoglobin relationship is the manner in which the dissociation curve steepens as arterial P o 2 falls below 60 mm Hg. WitrynaA special feature of the oxygen-hemoglobin dissociation curve is its tendency to buffer oxygen transport against significant drops in the pulmonary capillary oxygen tension. This is an important feature given that reduced pulmonary capillary oxygen tension is a common consequence of a large variety of pathologies along with breathing at High ...
