Lots of things. This question requires refineing.
Thymus
The lymphatic system works with the immune system.The lymphatic system consists of lymphatic vessels andlymphoid organs (lymph nodes, spleen, thymus gland, bone marrow)The functions of this system include absorption of excess fluid and its return to the bloodstream, absorption of fat (in the villi of the small intestine), andthe immune system function (help defend the body against disease).Examples of how lymphatic system helps the immune system:Bone marrow contains tissue that produces lymphocytes , which are white blood cells that mediate the immune response.Lymph nodes are concentrated with lymphocytes and macrophages(white blood cells)
thymus
The lymphatic capillaries are small, thin-walled vessels that collect excess tissue fluid (lymph) from the interstitial spaces and return it to the bloodstream. This helps maintain fluid balance in the body and plays a crucial role in the immune system by transporting immune cells and proteins.
Circulatory system
The lymphatic or lymphoid organ that decreases in size and in function as a person ages is the thymus gland. The thymus gland, which is situated in the chest area, is important because it plays a major role in the immune system. It is in this gland that T-cells are produced.
The thymus plays an important role in both the immune and endocrine systems.thymus

Circulatory system
A network of vessels, nodes, and organs called the lymphatic system collects the fluid that is lost by the blood returns it back to the circulatory system. The main functions of the lymphatic system are as follows: the main function of the lymphatic system is to collect and transport tissue fluids from the intercellular spaces in all the tissues of the body, back to the veins in the blood system; it plays an important role in returning plasma proteins to the bloodstream.
