  • 2. What does it mean to be fit?If you are fit, your body is well set up for exercise.For exercise your muscle cells need energy.Where does this come from? oxygen carbon dioxide respiration water glucose energyWhich organ systems provide the things you needfor respiration?
  • 3. ExploreHow much does pulse rate changewith different types of activities?
  • 4. Summary – Pulse rate activity1. Why does your pulse change when you do someactivities?2. Which activity gave the highest pulse rate?3. What sort of activity would give you a higherpulse rate?4. What might you be doing if you had a lowerpulse rate?5. When your heart is beating faster, what ishappening in your body?6. Why do different people have different pulserates?
  • 5. What process isthis animationshowing?Where is ithappening?How is this linkedto fitness andstamina?
  • 6. ExplainSequence correctly what happensinside our bodies when we run upand down the stairs.
