Verified step by step guidance

Step 1: Begin by understanding the components of the lymphatic system. The lymphatic system is a network of tissues and organs that help rid the body of toxins, waste, and other unwanted materials. It includes lymph nodes, lymphatic vessels, the spleen, thymus, and tonsils.

Step 2: Review the function of each listed organ. The thymus is a lymphatic organ responsible for the maturation of T-cells (a type of white blood cell). Lymph nodes filter lymph and house immune cells. The spleen filters blood and helps fight infections.

Step 3: Examine the adrenal glands. The adrenal glands are endocrine organs located above the kidneys. They produce hormones such as adrenaline and cortisol, which are not related to the lymphatic system.

Step 4: Compare the adrenal glands to the other listed organs. Since the adrenal glands are part of the endocrine system and not the lymphatic system, they are the correct answer to the question.

Step 5: Conclude that the lymphatic system does not include the adrenal glands, as they serve a different physiological function unrelated to lymphatic processes.
