Expert Answer

Step 1

The linkage between pulmonary ventilation and oxygen usage at the cellular level is provided by the cardiovascular system. During exercise, the working cardiac and skeletal muscles require an efficient amount of oxygen for maintaining aerobic conditions and other nutrients such as glucose, amino acids for the production of ATP. We breathe very fast to increase the rate of accumulation of oxygen in the lungs for the supply to muscle tissue thereby increasing the ventilation.

Step 2

The blood vessels dilate during exercise to allow the heavy flow of blood in the muscle tissue such that it can have an optimum amount of oxygen to provide the aerobic condition. This results in an increase in overall cardiac output.

Step 3

The sympathetic activity is increased and parasympathetic activity is reduced during exercise which causes the stroke volume and contractility of muscle to increase. Heart rate...
