The is fluid component of blood?

Plasma

Explanation:

The four major components of blood are – white blood cell (WBC), Red blood cell (RBC), Platelets and plasma. RBC constitutes 40% of the total blood volume and is essential cells that enable carrying of oxygen due to the presence of hemoglobin.

White blood cells are very less in number as compared to the volume of RBCs and are approximately 1/600 times the number of total red blood cells. WBC is responsible for defending our body against the infection. Platelets are also cellular particles that are found in the ratio of 1:20 to the RBCs and helps in clotting.  

The only liquid component of blood is plasma which consists of RBCs, WBCs and platelets. It constitutes more than 50% of the total blood volume.
