The answer is the third one: blood vessels.

Explanation for each option:

  1. The bone marrow: This is incorrect. While leukocytes are produced in the bone marrow, diapedesis refers specifically to the movement of leukocytes out of blood vessels, not their production or release from the bone marrow.

  2. The liver and spleen: This is incorrect. The liver and spleen are involved in filtering blood and recycling old blood cells, but diapedesis is not the movement of leukocytes out of these organs.

  3. Blood vessels: This is correct. Diapedesis is the process by which leukocytes move out of the circulatory system, specifically through the walls of blood vessels, to reach sites of tissue damage or infection.

In summary, diapedesis is the movement of leukocytes out of blood vessels, allowing them to reach and respond to areas of infection or injury in the body.
