Blood consist of a yellow fluid called plasma and different
types of blood cells such a red blood cells and white
blood cells
Red blood cells contain haemoglobin; a substance that carry
oxygen
The body needs oxygen to function and haemoglobin
carries the oxygen from the lungs and delivers it to
different parts of the body
Blood is red because of the iron content in the haemoglobin
Thalassaemia is a disease of red blood cells

3. Red blood cells There are millions of haemoglobin in each red
Each haemoglobin carries
4 molecules of oxygen (O2).
