unidirectional movement of WBCs directly to its target is?
- A- sliding
- B- phagocytes
- C- chemotaxis***
The correct answer is C. chemotaxis.
Here's why:
- Sliding:
This refers to the movement of cells along a surface, such as epithelial cells migrating during wound healing. While WBCs can utilize this movement within tissues, it doesn't involve direct targeting.
- Phagocytes:
These are a type of WBC that engulf and destroy foreign particles. While phagocytosis is a crucial function of WBCs, it's not the specific term describing their directional movement towards a target.
- Chemotaxis:
This is the directed movement of cells in response to a chemical attractant. In the case of WBCs, specific molecules released by bacteria, injured cells, or inflammatory processes act as chemoattractants, guiding the WBCs towards the source of the signal.
Therefore, chemotaxis accurately describes the unidirectional movement of WBCs directly to their target in response to chemical cues.
