Abstract
Blood is a vital fluid composed of plasma and corpuscular elements, which include red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes). These corpuscular components play essential roles in oxygen transport, immune defense, and blood clotting. Erythrocytes contain hemoglobin, allowing the efficient transport of oxygen to tissues and the removal of carbon dioxide. Leukocytes are crucial for the immune system, defending the body against infections and foreign invaders. Platelets contribute to hemostasis by forming clots to prevent excessive bleeding. Understanding the function and significance of these blood elements is fundamental in medical research, particularly in hematology and disease diagnostics. Advances in studying blood components have led to improvements in treatments for conditions such as anemia, leukemia, and thrombocytopenia. Pl
