Question

What is blood costing potting? Explain with the help of a flow chart only

Answer 1

Answer:

Explanation:

The injured cells and the platelets disintegrate at the site of the wound and release thrombokinase or thromboplastin.

Thrombokinase with the help of calcium ions converts prothrombin of the plasma into thrombin.

Thrombin in the presence of calcium ions reacts with the soluble fibrinogen and converts it into insoluble fibrin. Fibrin is a solid substance which forms threads and a meshwork at the site of the wound.

Blood cells are trapped in the network of the fibrin. The blood shrinks and squeezes out the rest of the plasma in the form of a clear liquid. The solid mass which is left behind is called a clot or thrombus.
