Plasma in the body is mostly made of what​

Explanation : Plasma is a pale yellow mixture of water, proteins and salts. One of the functions of plasma is to act as a carrier for blood cells, nutrients, enzymes, and hormones. 

Plasma is 90 percent water and makes up more than half of total blood volume. Other 10 percent is protein molecules, including enzymes, clotting agents, immune system components, plus other body essentials such as vitamins and hormones. 

• Helps to maintain blood pressure and keeps everything moving through the circulatory system, supplying critical proteins and serving as an exchange system for vital minerals.
• Plasma is frozen after collection and can be stored up to one year.
• Used to treat bleeding disorders when clotting factors are missing; plasma exchanges remove disease-causing factors from patient's plasma.
• Used to extract cryoprecipitate, a substance rich in Factor VIII, which is needed by hemophilia patients.
• Plasma purchased at for-profit centers is sold for research and some medical therapies.
