Solution
The correct option is A Diapedesis Whenever there is tissue damage, there will be inflammation at the site of damage (due to the release of chemicals). The blood cells particularly the leukocytes pass through the blood vessels of the circulatory system and move towards the site of tissue damage or infection. This migration of leukocytes to the site of tissue injury or inflammation is called Diapedesis. Hence, the correct answer is 'Diapedesis'.
