BLOOD
FLUID MATRIX PLASMA FORMED ELEMENTS
 Plasma
Plasma constitutes approximately 55% of blood and is
primarily composed of 90-92% water 
       and 6-8% proteins.
The major proteins in plasma are fibrinogen, globulins, 
       and albumins.
Fibrinogen plays a crucial role in blood clotting,
globulins are essential for immune defense
mechanisms, and albumins help maintain osmotic
balance
Plasma also contains small amounts of minerals like
sodium, calcium, magnesium, bicarbonate, chloride,
etc

Additionally, glucose, amino acids, and lipids are
present as they circulate through the body.

FORMED ELEMENTS
Erythrocytes, leucocytes and platelets are collectively called
formed elements and they constitute nearly 45 per cent of the
blood.
ERYTHROCYTES
Red blood cells (RBCs) are the most abundant cells in blood,
comprising approximately 5 million to 5.5 million per mm³ in a
healthy adult male
They are produced in the red bone marrow and lack a
nucleus in most mammals, adopting a biconcave shape
RBCs contain hemoglobin, a protein complex rich in iron, which
gives them their red color and enables them to transport
respiratory gases like oxygen and carbon dioxide
