Blood Basics: Getting to Know Your Blood
摘要
In this chapter, we explore the fundamentals of blood—what it is, what it’s made of, and why it is essential for life. We examine the major components of blood, including red blood cells, white blood cells, platelets, and plasma, and describe how each one contributes to maintaining health and balance within the body. The chapter also outlines how blood groups are determined, why they matter for transfusions, and how they influence compatibility between individuals.
