Sample Answer
Pre-game:
- Digestive enzymes break down meal while blood flow increases to stomach and intestines
- Circulatory system transports absorbed nutrients to muscle glycogen stores
Early Game:
- Blood flow shifts from digestive organs to muscles as stored energy is mobilised
- Digestive absorption slows while circulation prioritises oxygen and nutrient delivery
Mid-Late Game:
- Digestive system maintains blood glucose while circulation optimises muscle delivery
- Both systems work to balance hydration, energy supply and waste removal
