Understanding Blood: The Biological Perspective
Blood is an essential bodily fluid that sustains life through its vital functions. It is composed of several components, each playing a crucial role in maintaining health and ensuring the proper functioning of the body.
Components of Blood
- Red Blood Cells (Erythrocytes): Responsible for transporting oxygen from the lungs to tissues and returning carbon dioxide for exhalation.
- White Blood Cells (Leukocytes): Play a key role in immune defense, fighting infections, and protecting the body against disease.
- Platelets (Thrombocytes): Aid in blood clotting, preventing excessive bleeding when injuries occur.
- Plasma: The liquid part of blood that carries nutrients, hormones, waste products, and proteins.
Functions of Blood
- Transport of oxygen, nutrients, hormones, and waste products
- Regulation of body temperature and pH balance
- Protection against infection and blood loss
- Clot formation to prevent hemorrhage
Blood Types and Compatibility
Understanding blood types is critical for safe blood transfusions and organ transplants. The main blood groups are A, B, AB, and O, each with Rh factor positive or negative. Compatibility depends on matching these antigens to prevent adverse reactions.
