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

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.
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 substances to include fibrin, platelets and fibrinogen. The exception is an anticoagulant.
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
No, platelets and factors in the plasma are responsible for clotting. White blood cells mediate immunity.
