The Haemastamen , also known as the Blood Maker, is the 4th of the 19 gene-seed organs that are implanted into a Space Marine Neophyte to produce a new Astartes. Once implanted into a main blood vessel like the aorta, femoral artery or the vena cava, the Haemastamen alters an Astartes' blood's biochemical composition to carry oxygen and nutrients more efficiently. The actions of the Haemastamen turn a Space Marine's blood a brighter shade of red than that of normal humans because of its greatly increased oxygen-carrying capacity. It also acts to biochemically regulate the actions of the 2nd and 3rd gene-seed implants, the Ossmodula and Biscopea.
