- The Red Blood Cells
- The job of the red blood cells is to carry oxygen from the lungs to all the cells in the body.
- They have a biconcave shape to provide a large surface area for oxygen absorption.
- Cells contain haemoglobin containing lots of iron.
- Haemoglobin combines with oxygen n the lungs to form oxyhaemoglobin. But in body tissues the reverse happens to release oxygen to the cells.
- To allow more room for haemoglobin , red blood cells do not have a nucleus.
- Lack of Iron in the diet can lead to anaemia-This is the inability of the blood cells to carry enough oxygen.
