These animals do not have a bony skeleton. All insects are invertebrates. They do have a skeleton but it is on the outside of their bodies and is not made of bone. These two main groups have been divided into smaller groups.
There isn't an exact 'normal' figure for the number of cells in your blood (called your blood count). 'Normal' for a large man wouldn't be the same as for a small woman. But generally the normal white cell count is between about 4,000 and 11,000 cells per cubic millimetre of blood.here isn't an exact 'normal' figure for the number of cells in your blood (called your blood count).

How many white blood cells (WBCs) someone has varies, but the normal range is usually between 4,000 and 11,000 per microliter of blood. A blood test that shows a WBC count of less than 4,000 per microliter (some labs say less than 4,500) could mean your body may not be able to fight infection the way it should.
