Plasma might be mostly water, but it’s still one of the most essential substances in your body. It’s what gives your blood the ability to flow as a liquid, and it carries everything that your cells need to survive.

Plasma, in physics, an electrically conducting medium in which there are roughly equal numbers of positively and negatively charged particles, produced when the atoms in a gas become ionized.

Plasma, making up 99% of the visible universe, exists predominantly in stars and space. It forms when electrons detach from atoms, creating ions and free electrons, a state that can conduct electricity and exhibits complex behaviors.

What Is Plasma? An electrified, glowing gas that powers stars, lightning, and the quest for fusion energy, plasma is the most abundant form of matter in the universe.

Plasma is a state of matter created when a gas is heated or energized enough that electrons break free from their atoms. What remains is a mix of free-floating electrons, positively charged ions, and some intact neutral atoms.

Plasma is the fourth state of matter. Learn what it is, how it forms, its properties, types, examples, and how it differs from other states.

Plasma is made of water, proteins, hormones, and nutrients. Plasma plays a crucial role in overall health by transporting antibodies, clotting factors, and essential proteins throughout the body.
