Question

What is blood clotting ?

Answer 1

Hey !!

• It is a process of formation of blood clot after injury.
• 3-8 minutes is normal time of blood clot.
• Blood clotting is checked in blood vessels by the presence of anticoagulant (eg:- Heparin)
• Anticoagulant removes the cation to check the coagulation.
• Important components of blood clotting are fibrinogen , prothrombin , thromboplastin , calcium ions and vitamin-K
• Prothrombin protein of blood clotting is released by liver, while fibrinogen is synthesised in liver.
• Haemophilia is a genetic disease, in which blood clotting does not occur.

Good luck !!

Answer 2

                    BLOOD CLOTTING

⇒ After injury, there is formation of blood clot.

⇒ 3 to 8 is the normal time for blood clot

⇒ Blood clotting is checked in blood vessels by presence of anticoagulant that is heparin.

⇒ Anticoagulant removes the cation to check the coagulation.

⇒ Important components of blood clotting are --- fibrinogen, prothrombin, thromboplastin, calcium ions and vitamin - K.

⇒ Important steps of blood clotting are

⇒ Injury   →   Platelets broken released   →   Thromboplastin In the presence of ²⁺    Act upon

                           Prothrombin - (inactive)

                           Thrombin  - (active)

          (active thrombin change fibeinogen into fibrin)

           Fibrinogen    →   Fibrin (blood clotting)
