      red blood cells are transporters of oxygen in our blood. They collect oxygen from our lungs and take it to different parts of our body. They also have lots of iron inside, in haemoglobin. We change red blood cells all the time- they only stay alive for about 120 days! They are also called erythrocytes, pronounced: ih-rith-ruh-sytes.
