Verified step by step guidance

Step 1: Begin by understanding the function of the lymphatic system. The lymphatic system is responsible for transporting lymph, a fluid containing white blood cells, throughout the body to help maintain fluid balance and support immune function.

Step 2: Learn the structure and hierarchy of the lymphatic system. Lymph flows through a series of structures in a specific order: lymphatic capillaries, lymphatic vessels, lymph nodes, lymphatic trunks, and lymphatic ducts.

Step 3: Start with lymphatic capillaries. These are the smallest structures in the lymphatic system and are responsible for collecting interstitial fluid from tissues.

Step 4: Understand the role of lymphatic vessels. These larger structures transport lymph from the capillaries to the lymph nodes, where it is filtered and immune cells are activated.

Step 5: Follow the flow through lymph nodes, lymphatic trunks, and lymphatic ducts. Lymph nodes filter the lymph, lymphatic trunks collect lymph from larger regions of the body, and lymphatic ducts return the lymph to the circulatory system via the subclavian veins.
