Question
Why and when do the leucocytes perform diapedesis?
✓
Answer
- Diapedesis is the movement of leucocytes through the wall of blood capillaries into the tissue space.
- Leucocytes perform diapedesis as an important part of their reaction to tissue injury or infection.
- This process forms the part of the innate immune response, involving recruitment of non-specific leucocytes.
- Monocytes also use this process during their development into macrophages.
- Diapedesis helps leucocytes to perform their functions like phagocytosis, production of antibodies, secretion of inflammatory response chemicals, etc.
