Question

Diapedesis is the process by which red blood cells move into tissue spaces from the interior of blood capillaries. True or False

Answer 1

Answer: True

Explanation:

The diapedesis is the process by which the red blood cells in the body moves into the spaces in between the tissues from the interior side of the blood capillaries.

Most of the red blood cells are found in the post capillary venules because the shear forces are less in the venules.

This allows the red blood cells to attach easily to the walls of the vessels aand move out easily from it.

Answer 2

Answer:

False

Explanation:

Diapedesis is the process by which white blood cells move into tissue spaces from the interior of blood capillaries. It is the process of emigration of WBCs from the bloodstream. With the help of adhesion molecules, WBCs become attached to the endothelium of the blood vessels and squeeze between these cells. The adhesion molecules bind to the sugar moieties present on the surface of WBCs. Phagocytic WBCs such as neutrophils arrive at the site of infection by the process of diapedesis only.
