The coagulation cascade

This article is an approach to the physiology of coagulation. Several resources  (videos, animations and tutorials) are presented to help the reader learn the key coagulation factors and pathways.

Coagulation cascade: extrinsic, intrinsic and common pathways differentiation

Video animation contents:

  • Intrinsic pathway
  • Extrinsic pathway (endothelium exposure to VIIa factor).
  • Common pathway

Extrinsic, intinsic and common pathways

Hemostasis overview

The following animation depicts the process of hemostasis after endothelial damage (vasoconstriction, platelet adhesion, activation, interaction between coagulation factors and thrombin activation).

Coagulation cascade learning module

This tutorial features interactive exercises and animations that help understand the role of coagulation cascade factors and physiological hemostatic processes.

It highlights clinical disorders on intrinsic and extrinsic pathways, with a special section overviewing Von Willebrand’s disease.

Antiplatelet agents: mechanisms of action and general overview

This post is an overview on antiplatelet drugs, we will focus on the classification of agents and  their mechanism of action. The most relevant facts related to therapeutics will also be discussed here,  followed by a video review by  K.G. Paul, M.D. A related article explores the pharmacology of thrombolytic agents. Classification of antiplatelet agents…
