Read the following passage and construct a flow chart by matching the following events with their proper sequence. Physical exercise results in skeletal muscle contraction, an active process that requires chemical energy in the form of ATP. Initially, as contractions begin, small amounts of ATP are available within the skeletal muscle fibers; however, because of the limited stores of ATP, contractions may only be sustained for about 15 seconds before the ATP needs to be replenished. Cellular respiration is one mechanism by which muscle fibers produce and replenish their ATP. While cellular respiration increases the availability of ATP, it does so by consuming oxygen and glucose while producing water and carbon dioxide as a waste byproduct. Thus, during exercise, as the metabolic activity of the muscle fibers increase, the concentration of oxygen in the muscle tissue decreases. Other byproducts of metabolic activity (temperature, acidity, and CO2 concentrations) also increase as the muscle fibers continue to contract and consume glucose and oxygen. The increased presence of these metabolic byproducts is detected by specific homeostatic sensors that send out signals to the local vasculature and cause vasodilation, thereby shifting blood flow from less active tissues to the nearby exercising muscles. The greater flow of blood into the exercising muscle resolves the oxygen loss while simultaneously removing the waste and other byproducts of the increased metabolic activity.

What order should the following be in?
A) person starts to exercise
B) oxygen sensors cause local blood vessels to dilate
C) skeletal muscle oxygen demand increases
D) blood delivery to the skeletal muscles increases in order to provide more oxygen
E) skeletal muscle metabolism increases

I think it goes:
A, E, C, B, D
