Red blood cells
contain the oxygen carrying molecule haemoglobin; this is a special pigment that gives blood its red colour. Iron is needed in the production of haemoglobin; if your diet lacks this mineral you can develop the condition anaemia.

Arteries
Arteries carry blood away from the heart.

Veins
Veins carry blood back to the heart.
