Introduction to the lymphatic system

The video tutorial by Megan from Kenhub provides an in-depth look at the lymphatic system, explaining its importance, functions, and structure. It covers the system's role in clearing interstitial fluid, supporting the immune system, and transporting lipids. The tutorial also details the lymphatic vasculature and organs, including primary organs like the thymus and bone marrow, and secondary organs such as the spleen and lymph nodes. The video concludes with a summary of the key points discussed.
