b) The rate of oxygen transport by diffusion across the lungs must generally match the rate of transport by the circulatory system.
Explanation:
The respiratory and cardiovascular system works sin synchronization with each other to transport oxygen to tissue and eliminate carbondioxide.
example: Exercising skeletal muscles has increased metabolic rate which in turn cause increase requirement of oxygen and as a result increased carbondioxide will be produced.The body will function by releasing local metabolites which in turn effects on heart simultaneously blood vessels will dialates. The heart will pump more blood to deliver the oxygen and nutrient to match the metabolic requirement and will washout carbon dioxide.
