Coagulation of the blood begins with the activation of platelets - protoplasmic bodies that aid in the clotting of blood. These particles are part of blood composition at all times, but only coagulate when a blood vessel is injured. The injury triggers chemical signals which in turn draw collagen and platelets to the site of the wound and eventually build a structure to prevent blood loss.

∙ 7y agoA blood CELL doesn't start the process of clotting. Injury causes damaged tissue cells to produce prothrombin activator. This, along with clotting factor produced by the sticky platelets at the damaged site, cause prothrombin plus calcium to make thrombin.
All the while fibrinogen is stimulated to make fibrin. The fibrin ensnares RBCs to form the clot with the platelets. All factors have to be there for the clotting to occur. Lack of any of them causes bleeding disorders.

What are Proteins C and S?
Proteins C and S are two of the clotting factors that are present in the plasma to help regulate or activate parts of the clotting process
Do white blood cells initiate the clotting process?
No, platelets and factors in the plasma are responsible for clotting. White blood cells mediate immunity.
Why is positive feedback helpful in blood clotting but unsuitable for the regulation of body temperature?
Positive feedback accelerates the clotting process, but temperature would rise out of control.
What are blood clotting proteins?
Proteins involved in the blood clotting process form a barrier to stop the blood loose from injury. there are various blood clotting factors, thrombin, and fibrin are all involved in the biochemical cascade to make the fibrin clot at the end. They generally activated by each other from its precursor protein such as prothrombin, fibrinogen.
A chemical substance involved with clotting?
a chemical substance involved with clotting?
The process of clotting is called?
Coagulations
What is the clotting process called?
Hemostatis/ Haemostatis
What cells are involved in the clotting process?
Platelets.
What are the particles that help the clotting process?
platelets
What is the medical term meaning the process of clotting?
Coagulation is the medical term meaning process of clotting. Thrombogenesis is a related term meaning formation of a clot.
The clotting process in the blood directly involves all these substances EXCEPT?
The clotting process in the blood directly involves substances to include fibrin, platelets and fibrinogen. The exception is an anticoagulant.
What is the slowest step in the clotting process?
formation of prothrombin activator
These release substances that start the process of blood clotting?
platelets
What blood component is responsible for initiating the clotting process?
platlets
When do the fibers of the blood become visible?
During the clotting process
The slowest step in the clotting process is?
formation of prothrombin activator
Do white blood cells initiate clotting process?
No, platelets and factors in the plasma are responsible for clotting. White blood cells mediate immunity.
