Lymphatics of the mediastinum

This video tutorial explores the lymphatics of the mediastinum, focusing on the anatomy and function of major lymphatic vessels and nodes. It begins with an overview of the lymphatic system, followed by a detailed explanation of the mediastinum's structure. The tutorial then delves into the major lymphatic vessels, such as the thoracic duct, and the lymph nodes within the mediastinum. Clinical notes on lymphadenopathy highlight the importance of these structures in diagnosing conditions like cancer. The tutorial concludes with a summary of key points covered.
