Platelet plug is associated with

Options

A. Clot retraction
B. Haemostasis
C. Fibrin formation
D. Homeostasis

Answer

**Step-by-Step Solution:**

1. **Understanding Platelet Plug Formation**: The platelet plug, also known as the hemostatic plug or platelet thrombus, is formed through the aggregation of platelets. This occurs in response to injury in the blood vessel wall.

2. **Role of Platelets**: When there is an injury to the blood vessel, platelets are recruited to the site of injury. They have a sticky nature that allows them to adhere to each other and to the damaged area.

3. **Formation of the Plug**: The accumulation of platelets at the site of injury leads to the formation of the platelet plug. This plug serves to prevent excessive blood loss from the body by sealing the break in the blood vessel.

4. **Function of the Platelet Plug**: The primary function of the platelet plug is to stop bleeding and prevent contamination from external sources. It acts as a temporary barrier until further clotting processes can occur.

5. **Correct Association**: The platelet plug is specifically associated with hemostasis, which is the process that prevents and stops bleeding.

6. **Elimination of Other Options**:
- **Clot Retraction**: This refers to the shrinking of a blood clot over time and is not directly related to the initial formation of the platelet plug.
- **Fibrin Formation**: This process involves the conversion of fibrinogen to fibrin by thrombin, which occurs after the initial platelet plug formation.
- **Homeostasis**: While important for maintaining a stable internal environment, it is not directly related to the formation of the platelet plug.

7. **Conclusion**: Therefore, the correct answer to the question "Platelet plug is associated with" is hemostasis.
