Verified step by step guidance

Begin by identifying the primary components of the lymphatic system, which include lymph, lymph nodes, lymph vessels, and lymphoid organs such as the spleen and thymus.

Understand the role of the lymphatic system in maintaining fluid balance. It collects excess interstitial fluid from tissues and returns it to the bloodstream, preventing edema.

Explore the lymphatic system's function in immune defense. Lymph nodes filter lymph and house lymphocytes that respond to pathogens, playing a crucial role in protecting the body against infections.

Consider the other options provided in the problem. Recognize that hormone production for metabolism regulation is primarily a function of the endocrine system, not the lymphatic system.

Identify that breaking down food and absorbing nutrients is the function of the digestive system, and transporting oxygen to tissues is the role of the circulatory system, specifically the blood and cardiovascular system.
