Question

Mechanisms of blood clotting and How many plasma proteins involved in its mechanisms?​

Answer 1

Answer:

Blood clotting is a simple function dome for reducing the blood activity in a blood vessel.

Explanation:

Wjem a blood vessel gets affected either by getting cut or swelling or an accidental hit blood clottong is seen. Blood clotting has 3 important steps:-

1). The affected blood vessel firstly narrows down. Giving more friction for the blood flow and small opeaning for blood to continue its movement.

2). Platelets comes into picture here. Platelets segregates itself from serum and goes to the narrowed blood vessel site. These activated platelets turns from round shaped to spiny shape, so that they can attach themselves to affected blood vessel.

3). Fibrin protein gets activated now which forms a net like structure around the blood components such as RBC's. This entrapment does not allow blood to flow further.

With RBC's even platelets too get trapped which produces more of clot.

Answer 2

Mechanism of blood clotting

To explain the mechanism of blood clotting various scientist purpose different theories most accepted theory is cascade theory given by Mac-farlane and his -co worker.

ACCORDING TO THIS THEORY BLOOD CLOTTING IS COMPLETED INTO FOLLOWING THREE STEPS☑️

1. release of thromboplastin
2. conversion of prothrombin in thrombin
3. conversion of fibrinogen into fibrin.

1) Release thromboplastin

during blood clotting first of all the injured tissue released exothromboplastin and platelets release endotherboplastin .

These two thromboplastin unit together in the presence of calcium ions to form an enzyme called prothrombinase or thrombokinase.

2) conversion of prothrombin

prothrombin is an active plasma protein which is converted into its active form thrombin by the enzyme prothrombinase in the presence of calcium ions.

3) fibrinogen into fibrin

fibrinogen is a soluble plasma protein the mono mouse of fibrinogen are polymerised by thrombin to form insoluble fabria. fabria form a mein Fabrin network on cut or wound the blood cell get trapped in Fabrin network and hence blood clotting is take place after blood clotting a colourless fluid poses out of the cut on calcium which form a crust on cut or wound.

13 plasma protein are involved in blood CLOTTING.☑️
