GENERAL KNOWLEDGE

Detailed explanation-1: -Plasma is often called “the fourth state of matter, ‘’ along with solid, liquid and gas. Just as a liquid will boil, changing into a gas when energy is added, heating a gas will form a plasma – a soup of positively charged particles (ions) and negatively charged particles (electrons).

Detailed explanation-2: -When separated from the rest of the blood, plasma is a light yellow liquid. Plasma carries water, salts, and enzymes. The main role of plasma is to take nutrients, hormones, and proteins to the parts of the body that need it. Cells also put their waste products into the plasma.

Detailed explanation-3: -The word “plasma, ‘’ derived from the ancient Greek “to mold, ‘’ had been in use in medicine and biology for some decades when American chemist and physicist Irving Langmuir (1881-1957) began experimenting on electrical discharges in gas at the General Electric Research and Development Center in upstate New York.
