Name the cell or the blood part that fits each clue.
- The most numerous white cell. It eats germs.
- A cell with a kidney shaped nucleus. It also eats germs.
- A white cell that releases histamine, serotonin and heparin.
- The cell fragments that start the clotting. Name the cells that they break off from.

Need a reminder? The key ideaShow
Blood is about plasma and formed elements. A healthy adult has to million red cells in each mm³. The blood holds to g of haemoglobin in each mL in a woman and to g in a man. There are to white cells in each mm³. One mL is mm³. The white cells, from most to least: neutrophils, lymphocytes, monocytes, eosinophils, basophils.
The worked solution
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
Step 1. (a) The neutrophil, to of the white cells.
Step 2. (b) The monocyte. It is a phagocytic agranulocyte.
Step 3. (c) The basophil, which takes part in inflammation.
Step 4. (d) The platelets. They break off from the megakaryocytes of the bone marrow.
Step 5. (e) Albumin.
Answer: (a) neutrophil; (b) monocyte; (c) basophil; (d) platelets, from megakaryocytes; (e) albumin.
