Thrombocytes

Thrombocytes which are also known as blood platelets, are one of the many components - including the different types of cells that, together, form blood.


The structure of thrombocytes (or 'blood platelets') can be summarized as follows:

• Thrombocytes are cell fragments
• Disk-shaped
• Diameter 2-4 um (1 micro-metre = 1 um = 0.000001m)
• Have many granules but no nucleus
• Have a longevity of approx. 5-9 days.
• There are approx. 150,000 - 400,000 platelets per micro-litre of blood.

The functions of thrombocytes (or 'blood platelets') include:

• To facilitate blood clotting - the purpose of which is to prevent loss of body fluids.
