Answer to Question 1

ANS: D
Whenever hematopoiesis occurs outside the bone marrow in an adult, other than lymphopoiesis in lymphatic tissue, it is called extramedullary. This is abnormal.

Answer to Question 2

ANS: D
As mature blood cells come into contact with endothelial cells in the bone marrow, they bind to the surface via a receptor-mediated process. The binding creates a space between the luminal adventitial and endothelial cells. This allows the bone marrow cells to escape into circulation.
