Plasma Composition

When you hear the word blood, what do you picture in your mind? Most likely, your brain conjures up an image of thick, red liquid. But what would blood look like if you removed all the red cells? You’d be left with a murky yellowish liquid that would clear up once you removed the white cells and platelets. This lovely, clear, straw-yellow, liquid portion of blood is known as plasma.  So let’s talk about plasma composition.

After listening to this AudioBrick, you should be able to:

  • Define blood plasma and explain its importance and function.
  • Compare and contrast the contents of plasma and serum.
  • Understand how plasma components are used in medicine.

You can also check out the original brick on plasma composition from our Hematology collection, which is available for free.
