What is Plasma?

Plasma is the liquid part of your blood. It’s the clear, yellowish liquid portion of blood that remains after the cells and cellular components have been removed which includes the red blood cells, white blood cells and platelets.

Plasma is about 90% water and it makes up 55% of blood volume. Plasma contains cells, nutrients, proteins, enzymes, hormones, salts and more. Its primary objective is to move and transport material throughout the body to areas that are in need.

By doing so, plasma serves a variety of functions including helping to maintain a satisfactory and steady level of blood pressure as well as delivering proteins for blood clotting purposes and fighting various diseases. Plasma also helps to keep a pH balance, which is important for cells to function correctly for a healthy person.

The versatility of plasma makes it valuable for people who are sick. It is the essential ingredient for products crucial to treating patients suffering from many different life-threatening diseases and conditions, including hemophilia, shock or trauma, immune deficiencies and other blood disorders.
