Difference Between Plasma and Blood
The primary difference between plasma and blood is that plasma is in liquid form. It is a component of blood while blood is the main circulating fluid and is responsible for transporting important nutrients, oxygen, carbon dioxide and waste products to and away from the cells. The composition of blood is approximately 55% plasma and 45% blood cells. Plasma is a light yellow liquid that carries out water, salts, and some enzymes.
