When the blood vessel is injured, so is the endothelium, so it releases the endothelium tissue factor (TF), which complexes with factor VII, activating it, which then activates factor X and IX and the rest of the cascade continues.
Collagen is also exposed to a molecular, called high molecular weight kininogen (HMWK), prekallikrein and Hageman factor (factor XII), forming a complex. Prekallikrein is converted to Kallikrein and factor XII is activated to produced factor XIIa, which then activates factor XI and then factor X (the common factor between those two pathways), and the rest of the cascade continues, till the formation of the blood clot.
What else can I help you with?
Formation of thromboplastin?
Thromboplastin, also known as tissue factor, is released from damaged tissues or activated platelets during blood vessel injury. It initiates the extrinsic pathway of the coagulation cascade by forming a complex with coagulation factor VII, triggering the cascade that ultimately leads to the formation of a blood clot.
What factor initiates the coagulation cascade in vivo?
In vivo, the coagulation cascade is initiated by tissue factor (TF) which is exposed to blood following vessel injury. TF forms a complex with factor VIIa, leading to activation of Factor X and subsequent activation of thrombin, resulting in fibrin formation and clot formation.
What is the humoral coagulation system?
The humoral coagulation system refers to the protein coagulation factor component.
What is the significance of coagulation?
Coagulation is a process where solids begin to form, in a liquid. Like when your cut begins to scab over, that is coagulation.
What is coagulation of an egg?
what is blood coagulation?
Where is thromboplastin produced?
Thromboplastin, also known as tissue factor, is produced by subendothelial cells in blood vessel walls and by blood cells called monocytes and macrophages. Upon injury to a blood vessel, thromboplastin is exposed and initiates the extrinsic pathway of blood coagulation.
What is the abbreviation of The Initiates Program?
The abbreviation of The Initiates Program is TIP.
Who is the leader of The Initiates Program?
The leader of The Initiates Program is Jsarino.
Coagulation in cooking?
Coagulation is the thickening of a dish due to gelling of fat or gelatin.
What is coagulation value?

What word has a meaning similar to coagulation?
