Here's a taster:

Respiration isn't breathing in and out.
It's the process of releasing energy from glucose,
which happens constantly in every cell.
· Aerobic respiration needs plenty of oxygen.
Glucose + Oxygen Carbon Dioxide + Water (+
energy released)
· Energy released from respiration is used to
make ATP.
It's broken down to ADP when energy is
released.
ATP is synthesised from ADP using energy from
respiration.…read more

Here's a taster:

You respire more when you exercise.
More ATP is used to contract you're muscles so you
need more energy, so respiration increases.
Breathing rate increased to get more oxygen into
the blood.
Heart rate increases to get glucose and oxygenated
blood around the body to your muscle quicker, and
remove CO quickly at the same time.
· Anaerobic respiration doesn't use oxygen at all.
Sometimes you can't supply your body with all the
oxygen that it needs.
So in anaerobic respiration glucose lactic acid (+
energy released) and you produce energy but lactic
acid builds up in your muscles.
You need oxygen to clear up this acid, so you are in
an oxygen debt.
So you keep breathing for a while after you stop…read more

Blood is a fluid made of cells, platelets and
plasma.
Red blood cells ­ Transports oxygen from lungs
to all the cells in the body.
Plasma ­ Liquid that carries everything.
White blood cells ­ Fight infection from
microorganisms.
Platelets ­ Small cell fragments that help the
blood to clot.…read more
