2.4 The respiratory system : aerobic
GLUCOSE + OXYGEN = ENERGY + CO2 + H20
When the body continues an activity for a long time,
the energy produced using oxygen.
For it to work efficiently, oxygen must be constant.
THE ACTION OF BREATHING
1. When we breathe, the intercostal muscles raise
the ribs up and push out the sternum
2. This reduces the pressure inside the chest cavity
and causes air to be sucked into the lungs
3. The air is full of nitrogen, oxygen and low CO2
4. When we breathe out, the air is full of nitrogen,
CO2 and low oxygen.…read more
2.5 The respiratory system : anaerobic
GLUCOSE = ENERGY + LACTIC ACID
This occurs when there is insufficient amount of oxygen
Only used for short bursts
When we respire anaerobically, we use our glycogen stores in our muscles for energy. This is a
debt that we owe to the body. If not lactic acid builds up and aches the muscles. That's we do
a warm down and disperse the lactic acid.
We can do this by:
Expiration of breath
Excretion via urine and faeces.…read more
2.6 The Circulatory System
The blood carries the oxygen, water
and nutrients throughout the body and
transports and removes waste
Protection is provided when antibodies
that fight infection are carried in the
blood. Blood can clot to seal cuts and
Body temperature is regulated as the
blood carries it to lungs and skin where
it is released.
The Heart is a muscle which contracts and
relaxes (heartbeat). The rate will increase
when more oxygen is needed to supply the
