‘Carbon monoxide is a poisonous gas. There are around 50 deaths from carbon monoxide poisoning in the UK every year.
Carbon monoxide is breathed in and enters your bloodstream. It binds with
haemoglobin in the red blood cells. This means that the haemoglobin cannot bina
to oxygen so your blood cannot supply your body with the oxygen it needs.
Use your particle diagrams to explain how carbon monoxide affects red blood cells to
damage tissues, but carbon dioxide and nitrogen dioxide do not’.
