blood proteins are in capable of clothing inside the blood vessel but from blood clot at the side of the injury
Answers
Answer:
• Blood clotting takes place when platelets, a component of blood which promotes clotting is exposed to the air.
Explanation:
• Blood clotting is a necessary process that needs to be activated to reduce the excessive bleeding and for preventing the loss of blood through it.
• When there is a injury, the platelets reach the site of injury, and upon the exposure in the air initiates the process of clotting.
• But inside the cell, a powerful anticoagulant named Heparin is released by the liver, which prevents the blood to clot inside the blood vessels, namely the arteries and veins.
• But sometimes, due to abnormal functioning of the clotting mechanism or due to some genetic conditions blood can clot inside the body.
• And could not clott outside the body, that is in the case of injury. For example, in case of Heamophillia, the blood doesn't clott and the person can die due to excessive blood loss.
Answer:
Blood proteins, prothrombin and fibrinogen do not form blood clot inside blood vessels as these are in inactive form due to the presence of anticoagulant heparin. At the injury, these are activated by thrombokinase enzymes of bloods platelets.
