Lesson 4 20 STARTER Fill in the missing words to complete the paragraphs below: 1) are also known as ERYTHROCYTES. These blood cells are very, however there are of them within the human body. Their main job is to carry to the working muscles and cells within the body as well as transport to the lungs so it can be removed from the body. They contain a substance called which oxygen chemically attaches to, to create. This allows these cells to transport oxygen effectively around the body. These cells are produced in the of our bodies. 2) White blood cells are also known as. Their main role is to the body. They enable to body to infection and destroy. They are than red blood cells however there are of them within the bloodstream. 3) are small fragments of larger cells. Their role is to the blood e.g. they for a scab on the of the skin after a or. Clotting is massively important as it prevents the of blood.
