Answer 1

Hey mate!!

Process of blood-clotting

The mechanism to prevent excessive loss of blood from the body is called blood clotting.

Steps in blood clotting:

• At the site of cut, damaged cells and platelets release thromboplastin.
• This thromboplastin with the help of calcium ions,converts prothrombin into thrombin.
• In the presence of calcium ions,thrombin reacts with soluble fibrinogen and converts it into insoluble fibrin.
• Fibrin is a solid substance which forms threads and a meshwork at the site of cut.
• Blood cells trapped in the network of fibrin.The blood shrinks and squeezes out the rest of plasma in the form of clear liquid.
• The solid mass which is left behind is called clot.
