Migrate through blood vessels
Explanation:
White blood cells have the ability to perform diapedesis. Diapedesis refers to the emigration of white blood cells through the blood vessels. During the process, white blood cells move along the endothelium of blood vessels and stick to it. The white blood cells squeeze between the endothelial cells to migrate out of the blood vessels.
In this way, white blood cells can reach the site of infection or move from blood to the interstitial fluid to perform immune functions. The ability to migrate in and out of the blood vessels allows the phagocytic neutrophils and macrophages to arrive at the site of pathogen entry, basophils arrive at the site of inflammation to perform their respective functions.
