      Hey again mandeep101!

      Plasma could be two things!

      1) Blood plasma is a yellowish liquid in the blood that hold the various cells and is about 50-55% of the bloods total volume (so quite an important part!). It is made of water (mainly) but there are also some proteins in there such as albumin and fibronectin and also glucose, clotting factors, hormones etc… It is key to help us regulate protein levels which helps us with our water levels through osmosis!

      2) Plasma could also be used to describe one of the four fundamental states (solid / liquid / gas and plasma). It is basically an ionised gas! The sun is made up of a lot of plasma which is quite cool! Also lightening strikes produce plasma!

      Hope this helps you in your quest for plasma! Don’t forget to vote 🙂
