The term “hematology” originates from Greek, meaning “blood science.” Hematology is a specialized field that delves into the intricacies of blood and bone marrow, both in normal states and disease conditions. This discipline is pivotal as blood serves as a lifeline to the body, delivering vital substances and defending against external threats.
Understanding Blood Composition
Blood, the lifeforce coursing through our veins, comprises a fluid known as plasma and three distinct types of cells:
- Red Blood Cells (Erythrocytes): Responsible for oxygen transportation, these cells play a crucial role in maintaining energy levels and overall vitality.
- White Blood Cells (Leukocytes): Guardians of immunity, these cells shield the body against microbes and environmental agents, ensuring overall well-being.
- Blood Platelets (Thrombocytes): Essential for clotting, they prevent excessive bleeding, ensuring that even minor injuries do not pose a significant threat.
