Blood: Upper layer, buffy coat, lower layer, and anticoagulants (concept map)

Map summary:

This map is broken down into two parts I. the anti-coagulants used in blood analysis (which for some incredibly stupid reason, finds its way on many exams that healthcare students need to take. Note that calcium precipitates with phosphate which is pretty ubiquitous in the cell therefore EDTA is necessary for any genetic testing. and II: the components of blood that we can observe via centrifugation and their associated components.

There are three main layers of blood after centrifugation (separation by density and viscosity):

  • upper layer (plasma)
  • buffy coat (leukocytes and platelets)
  • lower layer (red blood corpuscles, which are also known as “bags of hemoglobin”)
