This lecture provides a structured and clinically integrated understanding of blood and hematopoiesis.

We begin with blood as a specialized connective tissue and examine its pathological relevance within a closed cardiovascular system. The discussion then connects each component of blood directly to disease mechanisms.

Topics covered:

• Plasma and formed elements
• RBC physiology and anemia–polycythemia correlations
• WBC alterations: leukopenia, leukocytosis, leukemia
• Platelet disorders: thrombocytopenia, thrombocytosis, bleeding mechanisms
• Plasma proteins and edema
• Plasma volume changes: shock and dehydration
• Hematopoietic stem cell concept
• Sites of hematopoiesis from fetal life to adulthood
• Regulation by erythropoietin, thrombopoietin and colony-stimulating factors
• Bone marrow failure and pancytopenia
• Extramedullary hematopoiesis

This session is designed for MBBS and allied health students who require conceptual clarity with pathological correlation rather than isolated memorization.
