When most people think about the body’s circulatory system, the heart and blood vessels often come to mind—but quietly working alongside it is the lymphatic system, a complex and essential network that plays a vital role in keeping us healthy. You've likely already encountered some aspects of this system in your study of immunity, fluid balance, and even cardiovascular function. This module will help you bring those pieces together into a clearer, more complete picture.

In this section, we’ll explore how the lymphatic system acts as both a drainage and defense network, moving fluid through lymphatic vessels, filtering it through lymph nodes, and supporting the immune response. You’ll learn how lymph, lymph nodes, the spleen, thymus, and tonsils all function in concert to protect the body. Whether you’re planning a career in nursing, allied health, fitness, or biology, understanding this system will deepen your grasp of how the body detects and responds to infection, maintains fluid balance, and even how cancer spreads. It’s a system that is often overlooked—until something goes wrong. By the end of this module, you’ll not only be able to identify its structures and explain its functions, but also connect it to real-world scenarios that you may encounter in your professional future.

1. Identify the components and anatomy of the lymphatic system (CLOs 1-2)
