What is the difference between aerobic and anaerobic respiration?
Aerobic respiration uses oxygen and produces a lot of energy.
Anaerobic respiration does not use oxygen and produces less energy, along with lactic acid.

Put these processes in order of what happens during digestion... (bonus if you can name where they happen!)
Egestion, Ingestion, Digestion, Absorption
Ingestion (swallowing and eating - mouth)
Digestion (breaking down food - stomach)
Absorption (absorbing nutrients into blood - small intestines)
Egestion (getting rid of waste - large intestine)

Carbon dioxide is a waste product from respiration. Put the journey it travels to be excreted into the correct order.
Bronchioles, Trachea, Heart, Mouth/Nose, Alveoli, Bronchi
Heart > Alveoli > Bronchioles > Bronchi >Trachea > Mouth/Nose

When you exercise you need more glucose and oxygen for respiration, what does this cause?
Your heart rate to increase - your heart beats faster to pump more blood (that carries glucose and oxygen) around your body to the cells that need it for exercise.
