Verified step by step guidance1
Identify the role of the lymphatic system in the body, which includes returning interstitial fluid to the cardiovascular system, supporting immune function, and absorbing dietary fats.
Understand that lymphatic vessels are responsible for collecting and returning excess fluid from tissues back to the bloodstream, thus maintaining fluid balance.
Recognize that lymphoid organs, such as the spleen and lymph nodes, play a crucial role in supporting the immune system by filtering pathogens and housing immune cells.
Learn that lacteals are specialized lymphatic vessels located in the small intestine that absorb dietary fats, which are too large to enter blood capillaries directly.
Match each function with the correct component of the lymphatic system: vessels return fluid, lymphoid organs aid immune function, and lacteals absorb fats.
