Question

Given is diagram depicting a physiological process in man.
Name the process occurring in the diagram.

Answer 1

The process occurring in the diagram is diapedesis. Diapedesis is the movement of blood cells (particularly leucocytes) from the capillaries into the tissue fluid (i.e the site of tissue damage during an inflammation). The process helps in the recruitment of white blood cells (leucocytes) during the immune response to inflammation.
