Abstract

Blood is a vital fluid responsible for oxygen transport, immune defense, and homeostasis. It is composed of plasma (55-60%) and formed elements (40-45%), including erythrocytes (red blood cells), leukocytes (white blood cells), and thrombocytes (platelets). Hemoglobin, found in erythrocytes, plays a crucial role in oxygen and carbon dioxide exchange. Leukocytes provide immunity against infections, while platelets facilitate blood clotting. Osmotic pressure, blood viscosity, and pH levels regulate fluid balance and circulation. Understanding blood composition and disorders such as anemia, erythrocytosis, leukocytosis, leukopenia, thrombocytopenia, and hemolysis is essential for medical diagnostics and treatment.
