Blood (Earth-1791)

Blood is used to transport nutrients through the body of a multicellular organism. In the case of 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. The same is applied to all of the other sentient species, being from the Halo Council, or the Blood Covenant, though their blood are delivering a different compound to the body, resulting in its difference in color to Human blood.

Overview
Prothean artifacts, such as the Menachite Engineer Complex, may at times be manipulated by Human blood.

When shot without the protection of an energy shield, the target will "bleed." In some species, the blood will visibly come out of the target, and leave a stain on the ground. The viscosity and color of the blood varies by species.
