Key terms
Cardio-respiratory
system
The name used to describe the respiratory system and cardiovascular
system working together
Gaseous exchange
The process where oxygen from the air in the alveoli moves into the blood in
the capillaries, while carbon dioxide moves from the blood in the capillaries
into the air in the alveoli.
Haemoglobin
The protein found in red blood cells that transports oxygen (as
oxyhaemoglobin) and carbon dioxide around the body.
Oxyhaemoglobin
A chemical formed when haemoglobin bonds to oxygen.
Alveoli
Small air sacs in the lungs where gaseous exchange takes place.
Capillaries
A network of microscopic blood vessels. They are only one cell thick.
Diffusion pathway
The distance travelled during diffusion. The diffusion pathway is short in
gaseous exchange.
