Coagulation Cascade - Easy Way To Remember Intrinsic vs Extrinsic Pathways | PT or PTT?

The coagulation cascade is easily forgotten. I show you an easy way to remembering intrinsic vs extrinsic pathways, as well as whether PT or PTT
is the test needed. I also go through how different anticoagulants work on the coagulation cascade.

    Hi Shelice! Generally speaking, we'd mainly be looking at trauma- which is of course a situation where coagulation would be a physiological attempt to reduce blood loss. There are of course others, but there are technical differences. Endothelial dysfunction, for example, may result from many causes including smoking, hypertension, diabetes mellitus, dyslipidemia etc. Endothelial dysfunction has been shown to contribute to the pathogenesis of thrombosis, but this is more of a pathological process rather than a physiological process seen in response to trauma! Hope that helps somewhat. Thanks for watching!

    Hi Stacy! Thank you! (Also for the coffee!! 😁). I'm so glad it helped - as for the Factor V, you are absolutely correct that Factor IV is a calcium ion, in the video I say that Factor V is needed alongside a Calcium Ion, I can see however how it could cause confusion as they're listed together- I should have made it clearer! Thank you again for your support, it really means a lot. All the best with your exam :)
