Skeletal System Function & Organs | What is the Skeletal System? Lymph nodes also filter cellular waste, dead cells, and cancerous cells. Lymph also carries the molecules that are too large to diffuse through the capillary wall (e.g. spleen, thymus gland, tonsils, Peyer's . While your lymph nodes filter lymph, your spleen filters blood to remove bacteria, viruses and other foreign materials. The lymph helps large molecules that cannot diffuse through the capillary wall to enter the blood, like proteins or lipids. The 5 main functions of the lymphatic system include: Draining the lymph from the tissues: The lymphatic system drains the lymph (extra fluid) leaking from the body tissues and returns it to the blood system. The three functions of the immune system include maintaining the levels of body fluids, assisting the immune system, and absorbing cellular waste and digestive fats. The functions of the lymphatic system complement the bloodstream functions, as it regulates the balance of fluids in the body and filters the pathogens from the blood.
