Composition of normal human blood determined by FTIR
Authors

Abstract
Blood is a vital liquid tissue, representing approximately 7–8% of
total body weight, and performs essential transport, defense, and regulatory
functions. Its composition consists of two main parts: plasma and formed
elements. Plasma, which constitutes approximately 55% of blood volume, is a
straw-yellow liquid composed of ~90% water, 7–8% proteins (albumins, globulins,
fibrinogen), and 2% other constituents (electrolytes, nutrients, hormones,
waste products). Formed elements, which represent approximately 45% of the
volume, include erythrocytes (red blood cells, responsible for transporting
oxygen and carbon dioxide), leukocytes (white blood cells, involved in immune
defense), and platelets (essential for hemostasis and coagulation). Normal
values vary depending on sex, age, and physiological state, but maintaining a
balance between these components is crucial for the body's homeostasis.
