Plasma is the aqueous portion of the blood, the acellular portion in which the cellular portions are suspended and transported. It also contains electrolytes and substrates from digestion, such as glucose, fatty acids, and proteins. Hormones also are transported in this part of the blood.
In electrical engineering, ground or earth is the reference point in an electrical circuit from which voltages are measured, a common return path for electric current, or a direct physical connection to the Earth.trictly speaking, the terms grounding or earthing are meant to refer to an electrical connection to ground/earth. Bonding is the practice of intentionally electrically connecting metallic items not designed to carry electricity.
A  grounding electrode conductor  is the conductor between a common single grounding point in the system and the grounding electrode.  Bond  refers to the connection between the grounded conductor, the equipment grounding conductors and the grounding electrode conductor.Bonding is also used to describe connecting all of the exposed metal surfaces together to complete the equipment-grounding conductors.n some areas, the term earthing is used instead of grounding. A  grounded conductor  is a current-carrying conductor that normally carries current and is also connected to earth. Examples are the neutral conductor in AC wiring and the negative conductor in many DC systems.
