Migration of phagocytes and other leucocytes towards the place of infection occurs through

Options

A. Thrombosis
B. Diapedesis
C. Emboly
D. Phagocytosis

Answer

**Step-by-Step Solution:**

1. **Understanding the Context**: When there is an injury or infection in the body, the immune system responds by sending white blood cells (leukocytes) to the site of infection. This process is crucial for fighting off pathogens.

2. **Role of Phagocytes and Leukocytes**: Phagocytes, a type of leukocyte, play a vital role in the immune response. They are responsible for engulfing and digesting cellular debris and pathogens, a process known as phagocytosis.

3. **Mechanism of Migration**: The migration of these immune cells to the site of infection occurs through a process called diaphoresis. This involves the movement of white blood cells out of the bloodstream and into the tissues where they are needed.

4. **Diapedesis Explained**: Diapedesis is the process where leukocytes squeeze through the endothelial cells of blood vessels to reach the infected area. This is facilitated by various signaling molecules that attract the leukocytes to the site of infection.

5. **Chemotaxis**: Once the leukocytes have migrated to the site of infection, they are guided by chemotactic signals (chemotaxis) that direct them to the exact location where they are needed.

6. **Conclusion**: Therefore, the correct answer to the question is that the migration of phagocytes and other leukocytes towards the place of infection occurs through **diapedesis**.
