diapedesis

(di?a-ped-e'sis) [? + pedan, to leap]
The movement of white blood cells and other cells out of small arterioles, venules, and capillaries as part of the inflammatory response. The cells move through gaps between cells in the vessel walls.

diapedesis

The passing of blood cells through the intact CAPILLARY wall into the tissue spaces. Diapedesis is a feature of INFLAMMATION.

diapedesis

the passage of white blood cells through the unruptured wall of a blood vessel by changing in shape; an important reaction to tissue injury, leading to inflammation.

diapedesis
