<p>The haematopoietic cells produce the vast majority of blood cells in the body ([[Haematopoiesis - Overview|haematopoiesis]]). In young animals this occurs in most bones in the body but in mature adults this is limited to membranous bones in the body.</p>

<p>To enter circulation newly formed cells press against the sinusoid wall, temporally fusing to it and creating an opening. The cell then passes directly into the circulation and the membrane repairs itself. Mature [[Erythrocytes|erythrocytes]] immediately enter circulation, however the marrow stores [[Leukocytes|leukocytes]] and consequently contains around ten times more [[Leukocytes|leukocytes]] than found in circulation</p>
