Explanation:
The clotting of blood, also known as coagulation, is a vital process that helps to seal up wounds and prevent excessive blood loss. It involves a series of complex reactions that result in the formation of a blood clot, which acts as a temporary plug to stop bleeding.
Explanation of each option:
1. Slow down the movement of blood inside the blood vessel: This option is not correct. The clotting of blood does not slow down the movement of blood inside the blood vessel. Instead, it helps to stop bleeding by forming a clot at the site of injury.
2. Trap oxygen inside the blood so that it may be transported more easily: This option is not correct. The primary function of blood clotting is not to trap oxygen but to prevent excessive blood loss. Oxygen is carried by red blood cells, and clotting does not directly affect their ability to transport oxygen.
3. Seal up wounds to avoid loss of blood: This option is correct. The main purpose of blood clotting is to seal up wounds and prevent the loss of blood. When a blood vessel is damaged, platelets in the blood stick together and form a plug at the site of injury. This plug is then reinforced by a network of thread-like proteins called fibrin, which forms a clot and seals the wound.
Conclusion:
In summary, the clotting of blood is a crucial process that helps to seal up wounds and prevent excessive blood loss. It does not slow down the movement of blood or trap oxygen inside the blood. Therefore, the correct answer is option 'C': "Seal up wounds to avoid loss of blood."
