Blood is made up of blood cells (also called hematocytes or hematopoietic cells) and plasma . These are the cellular components of the blood covering about 45 – 46% of total blood. There are four types of blood cells present in humans, namely, (i) Red Blood Cells (RBCs), (ii) White Blood Cells (WBCs), and (iii) Platelets. Understanding the biochemical composition of blood is crucial for diagnosing diseases, monitoring health status, and advancing medical research. Clinical biochemistry reveals the molecular mechanisms of various physiological and pathological conditions by analyzing the components of blood in detail. Why Study Blood Biochemistry? Blood is the body fluid in humans and other animals that delivers the essential materials for life to the body's cells. It has sometimes been called a fluid “tissue,” because like solid tissues it contains several types of cells which perform complex functions for the human body. Blood is a fluid connective tissue circulating through blood vessels. There are two components in the blood , fluid component (plasma) and cellular elements (red blood cells, white blood cells, and platelets). Each of the components plays different roles which in...
