Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If the skin is broken then a blood clot forms to seal this cut.What is the first step in the process of blood clotting?
A
Fibrinogen turns into fibrin
B
Platelets release clotting factors
C
Fibrinogen is converted into thrombin
D
Thrombin is converted into prothrombin
Explanation: 

Detailed explanation-1: -Primary hemostasis is when your body forms a temporary plug to seal an injury. To accomplish that, platelets that circulate in your blood stick to the damaged tissue and activate. That activation means they can “recruit” more platelets to form a platelet “plug” to stop blood loss from the damaged area.

Detailed explanation-2: -1) Constriction of the blood vessel. 2) Formation of a temporary “platelet plug.” 3) Activation of the coagulation cascade. 4) Formation of “fibrin plug” or the final clot.

Detailed explanation-3: -A platelet plug is formed, and the external bleeding stops. Next, small molecules, called clotting factors, cause strands of blood-borne materials, called fibrin, to stick together and seal the inside of the wound. Eventually, the cut blood vessel heals and the blood clot dissolves after a few days.

Detailed explanation-4: -The three steps to platelet plug formation are platelet adherence, activation, and aggregation.

Detailed explanation-5: -Platelets are tiny blood cells that help your body form clots to stop bleeding. If one of your blood vessels gets damaged, it sends out signals to the platelets. The platelets then rush to the site of damage and form a plug (clot) to fix the damage.
