=== Cell types ===
All blood cells are divided into three lineages.<ref>{{Cite web |title=Hematopoiesis from Pluripotent Stem Cells |url=http://www.ebioscience.com/resources/pathways/hematopoiesis-from-pluripotent-sem-cells.htm |access-date=25 April 2020 |website=Antibodies Resource Library |publisher=ThermoFisher Scientific}}</ref>
* [[Red blood cell]]s, which are also called erythrocytes, are the oxygen-carrying [[red blood cell|cell]]s. [[Red blood cells|Erythrocytes]] are functional, and are released into the blood. The number of reticulocytes, which are immature red blood cells, gives an estimate of the rate of [[erythropoiesis]].
* [[Lymphocyte]]s are the cornerstone of the adaptive immune system. They are derived from common lymphoid progenitors. The lymphoid lineage is composed of [[T-cell]]s, [[B-cell]]s, and [[natural killer cells]]. This is [[lymphopoiesis]].
* Cells of the myeloid lineage, which include [[granulocyte]]s, [[megakaryocyte]]s, monocytes, and [[macrophage]]s, are derived from common myeloid progenitors, and are involved in such diverse roles as [[innate immunity]] and [[blood clotting]]. This is [[myelopoiesis]].

[[Granulopoiesis]] (or granulocytopoiesis) is haematopoiesis of granulocytes, except [[mast cell]]s which are granulocytes but with an extramedullar maturation.<ref>{{Cite book |last=Mahler |title=Haschek and Rousseaux's handbook of toxicologic pathology |date=2013 |publisher=Academic Press |others=associate editors, Brad Bolon and Ricardo Ochoa; illustrations editor, Beth W. |isbn=978-0-12-415759-0 |editor-last=Haschek |editor-first=Wanda |edition=Third |location=[S.l.] |page=1863 |editor-last2=Rousseaux |editor-first2=Colin G. |editor-last3=Wallig |editor-first3=Matthew A.}}</ref>

[[Thrombopoiesis]] is haematopoiesis of [[Platelet|thrombocytes (platelets)]].
