Blood contains the blood cell and plasma.

BLOOD CELLS

Three types of cells are present in blood

 • Red blood cell or erythrocyte

 • White blood cell or leukocytes

 • Platelets or thrombocytes

PLASMA

 • Plasma is a straw coloured clear liquid part of blood.

 • It contains about 91% of water and about 9% of solid

 • The solid at the organic and inorganic substance.

SERUM

 • Serum = plasma - fibrinogen

 • Serum is the clear straw coloured fluid that oozes from blood clot.

 • Serum contains all other constituent of plasma except fibrinogen.

 • Fibrinogen is absent in serum because it is converted into fibrin during blood clotting.
