Blood Plasma

Question 1

What is blood plasma?

Answer 1

A straw-colored liquid in which blood cells are suspended.

Blood plasma is mostly water (90% to 95%). The remainder of plasma is solutes, mostly plasma proteins, such as albumin, globulins, and fibrinogen. In addition to plasma proteins, plasma contains other solutes, such as electrolytes (sodium, potassium, calcium ions), dissolved gases (oxygen, carbon dioxide), nutrients (vitamins, minerals, lipids, glucose, amino acids), hormones, and metabolic wastes.
