AVO2 difference is low as not much O2 is required by muscles

Question 2

Is AVO2 difference high or low during exercise + why?

Answer 2

AVO2 difference is high as more O2 is required by the muscle so haemoglobin disassociates more readily. More haemoglobin is unsaturated at venous end

Question 3

What is the impact of a greater AVO2 difference

Answer 3
