Blood is used to transport nutrients through the body of a multicellular organism. In the case of [[human|humans]], it uses a compound called hemoglobin to transport [[oxygen]] to the cells. Because of cellular respiration, every single cell in the human body needs oxygen, so blood must deliver oxygen to every cell in the body. This is most likely true all of the other [[Covenant]] races, though their blood may be delivering a different compound to the body. | Blood is used to transport nutrients through the body of a multicellular organism.
