A primer on platelets
Blood is red. That’s because of the red blood cells or erythrocytes that whizz around your veins and arteries. The colour is a great visual marker, both clinically and emotionally, but sometimes its very redness hides the other important components that are in you to give. These include plasma, the straw-coloured liquid that carries red blood cells, white cells (leukocytes), other important molecules such as albumin, antibodies and coagulation factors, and tiny fragmentary cells called platelets.
