Bleeding and impaired hemostasis

4 videos

Hemostasis

VIDEO 6:25 minutes
Hemostasis is the process which stops bleeding after an injury. Blood vessels are repaired by the creation of a platelet plug during primary hemostasis, and the platelet plug is further reinforced by the conversion of fibrin to fibrinogen ...

Primary hemostasis

VIDEO 10:51 minutes
During primary hemostasis, a platelet plug is formed to rapidly stop the initial bleeding after injury. Learn about the different steps involved in primary hemostasis: vasoconstriction, platelet adhesion, activation and degranulation, ...

Secondary hemostasis

VIDEO 3:57 minutes
Secondary hemostasis is the process where the platelet plug initially created in primary hemostasis is reinforced by the conversion of fibrinogen to fibrin.

Anticoagulation and thrombolysis

VIDEO 10:25 minutes
Anticoagulation is the process that prevents clots from forming. Thrombolysis is the process of breaking down clots after they’ve been formed. Learn how the antithrombin III interacts with heparin-like molecules and how plasmin breaks down ...
