Student doctors often run screaming from this topic as it can be very complex with seemingly endless nonsensical Roman numerals that make up the biochemistry of the clotting cascade.
But we’re here to make it simple, by going at it in bite sized pieces that will in time build into a whole picture of coagulation enabling you to understand the science behind why you had a clot and how your medication works.
Today’s quiz covers the basic ground work about blood, then we’ll have two posts on the absolute basics of clotting which can be covered by two swear word innuendos,
- taking the Pxxs
- the ‘F’ words
So – What’s in your blood?
Although it looks like a red liquid, blood is actually a straw-coloured liquid that has blood cells floating around in it.
If blood is allowed to settle you can see this clearly by the three layers that form
- At the bottom is a deep red layer containing the red blood cells
- Then a thin whitish layer or buffy coat, composed of white blood cells and platelets.
- At the top is plasma; the liquid part of the blood
If a drop of blood is spread thinly on a microscope slide, it’s called a film. A blood film shows just how many more red cells than white cells there are.
