The lymphatic system is a vital component of the circulatory and immune systems, making its study essential for B.Pharm students. It plays a crucial role in maintaining fluid balance, absorbing fats, and defending the body against pathogens. Understanding the functions of lymphatic organs, the circulation of lymph, and its interaction with the bloodstream provides a critical framework for comprehending immunology, drug distribution, and the body’s response to infections and therapies.
