Learn what blood plasma and physical plasma are, their composition, how they’re produced, and why they matter in medicine and technology.

Blood plasma is the liquid component of blood that carries proteins, nutrients and waste, while plasma in physics refers to an ionized gas that conducts electricity. Both share a name but differ vastly in composition and applications, a distinction first noted by Irving Langmuir who likened ionized gas to the fluid that carries cells in the bloodstream【2】.  

**Key takeaways**  
- Blood plasma makes up about 55 % of total blood volume and is roughly 95 % water【1】.  
- It contains essential proteins such as albumin, globulins and fibrinogen that regulate osmotic pressure and clotting【1】.  
- Physical plasma is a state of matter where a gas is ionized, containing free electrons and ions, and makes up most of the visible universe【2】.  
- Plasma’s electrical conductivity enables technologies like plasma TVs and etching, and it occurs naturally in stars and lightning【2】.  
- The term “plasma” was borrowed from blood plasma to describe the carrier role of ionized gas in electrical phenomena【2】.  

## Blood Plasma: Composition and Medical Role  

Blood plasma is a light amber‑colored fluid that remains after blood cells are removed, retaining dissolved proteins (6–8 % of its volume), glucose, electrolytes, hormones and gases【1】. Albumins, the most abundant plasma proteins, maintain osmotic pressure and are produced in the liver, while globulins—including immunoglobulins—support immune function and transport substances like lipids【1】. Fibrinogen, another key protein, enables clot formation to prevent bleeding【1】.  

Clinically, plasma can be separated by centrifugation after adding an anticoagulant, a process called blood fractionation【1】. Fresh frozen plasma is listed on the WHO Model List of Essential Medicines because it is vital for treating trauma‑related blood loss and is stocked in hospitals and ambulances worldwide【1】. Compared with serum, plasma yields a larger sample volume and requires less waiting time before analysis, though the addition of anticoagulants can introduce measurement errors【1】.  

## Physical Plasma: Ionized Matter in Nature and Technology  

Physical plasma arises when a gas undergoes significant ionization, creating a mixture of ions and electrons that conducts electricity【2】. It dominates the cosmos, comprising roughly 99.9 % of ordinary matter, and forms the core of stars and the intergalactic medium【2】. On Earth, partially ionized plasmas appear in neon signs and lightning, while fully ionized plasmas can be generated by heating gases or applying strong electromagnetic fields【2】.  

The conductive properties of plasma are harnessed in modern devices such as plasma display panels and in industrial processes like plasma etching, which shapes microelectronics【2】. Langmuir’s 1928 adoption of the term “plasma” was inspired by the analogy to blood plasma’s role as a carrier medium, highlighting the conceptual link between the two distinct phenomena【2】.  

## Why it matters  

Understanding blood plasma is essential for medical diagnostics, transfusion medicine, and emergency care, as its proteins and clotting factors are critical to patient survival. Meanwhile, knowledge of physical plasma underpins advances in energy, communications and manufacturing, given its prevalence in stars and its utility in high‑precision technologies. Both forms of plasma illustrate how a single term can bridge biology and physics, reminding researchers and clinicians alike of the interdisciplinary nature of scientific discovery.
