Blood, the river of life, is a critical area of study for B.Pharm students. Understanding its composition, from plasma proteins to the various formed elements, and its vital functions like transport, immunity, and hemostasis, is essential. This knowledge forms the bedrock for learning about hematological drugs, transfusion medicine, and the pharmacokinetic profile of countless therapeutic agents.
