The 3 stages of hemostasis are:

1) Vascular Spasm where there is a high resistance to blood flow as arterioles leading to the damaged area vasoconstrict.

2) Platelet Plug: is wher sticky cell fragments adhere to the site of the damaged blood vessel and the aggregated platelets secrete Adenosine Diphosphate causing more platelets to aggretage and congrugate around the blood vessel

3) Blood Clots: blood clots become trapped in fibrin mesh....fibrin comes from fibrinogen and goes through a process to form fibrin called coagulation cascade. The fibrin adhere to one another forming a mesh. The mesh becomes stronger by Factor VIII stabalizing the bond on the fibrin.

Does whole blood have clotting factors?

Yes, whole blood contains clotting factors such as fibrinogen, prothrombin, and platelets that help initiate the blood clotting process.


Do white blood cells initiate the clotting process?

No, white blood cells do not initiate the clotting process. Clotting is primarily initiated by platelets and clotting factors in the blood. White blood cells play a role in the immune response to infection and inflammation.


What is the slowest step in the clotting process?

The activation of factor X to Xa is typically considered the slowest step in the clotting process. This step involves multiple protease activations, which can take more time compared to other steps in the clotting cascade.

What is the mineral necessary for chemical clotting?

Calcium is the mineral necessary for chemical clotting. It plays a crucial role in the blood clotting process by enabling the activation of various clotting factors and facilitating the formation of a stable blood clot.


How does coagulation work in the process of blood clotting?

During blood clotting, coagulation is the process where blood changes from a liquid to a gel-like state to stop bleeding. It involves a series of chemical reactions that lead to the formation of a fibrin clot, which helps seal the wound. This process is triggered by platelets and various clotting factors in the blood.


The clotting process in the blood directly involves all these substances EXCEPT?

What is the smallest formed elements in the blood and they play important role in the blood clotting?

Platelets, or thrombocytes, are the smallest formed element in the blood. Made of cell fragments, platelets are part of the blood clotting process. Non-formed clotting factors also are critical to blood clotting.thrombocytes
