Sample Answer

The respiratory and circulatory systems respond to movement through increased oxygen demand:

Breathing rate increases to supply more oxygen
Heart rate increases to transport oxygen more rapidly
Blood flow is redirected to working muscles

Signs of system stress requiring first aid include:

Abnormal breathing patterns or respiratory distress
Irregular pulse or extreme heart rate
Dizziness or light-headedness

First aid responses should:

Position person appropriately (seated for respiratory, lying for circulatory)
Monitor vital signs
Cease activity and implement STOP protocol if needed
