The Lymphatic System is in charge of transportation of lymph fluids. The lymph is secreted from different tissues and organs. This helps keep your body healthy.The function is to keep a proper level of fluid in the body’s cardiovascular system. It picks up extra interstitial fluids (lymph) and returns the proteins and nutrients left behind, while also collecting wastes and lipids. The immune helps the lymphatic system maintain homeostasis. Vessels: One-way flow, to the heart.Lymph Fluid: Clear and watery. Sometimes called interstitial fluids. Contains some proteins.Lymph Nodes: Located around the body, vessels pass through them and contain capillaries.Lymph Organs: Spleen, Thymus, Tonsils, Peyer’s Patches, Appendix.Leukocytes: T and B Cells.Just like other vessels in the body, the lymphatic vessels have capillaries. The capillaries surround loose connective tissues and draw up extra fluids towards the heart in one direction only. Lymph nodes help play a vital role in cleansing the lymph and also defending the body against infection.Lymph organs: The spleen, thymus, tonsil, appendix, and Peyer’s Patches. The spleen has the job of cleansing the blood via macrophages. The thymus houses T cells. Tonsils and other mucous membranes like Peyer’s patches and the appendix help defend and protect our bodies mucous. Our Peyer’s patches are located in the small intestine and the appendix an organ attached to the large intestine.The pharyngeal, Palatine and inguinal tonsil are associated with the mucous membranes of the lymphatic system. B cells are generated in bone marrow and the T cells in the thymus.The Immune System works closely with the integumentary and lymphatic systems. The skin and mucous membranes the bodies first line of defense against pathogens trying to enter the body. The cilia of the mucous membranes help by trapping debris and invaders.This system is comprised of different leukocytes used to aid in defense and maintain homeostasis within the body. The white blood cells, macrophages, and neutrophils are used. A different type of cell, known as the Natural Killer cell also helps aid in immunity. The Natural Killer cells help destroy cancer cells and virus-infected cells. Immunity Types: Adaptive Immunity and Innate Immunity. Adaptive Immunity uses memory. Once infected, the immune system senses and destroys whatever pathogen that has tried to enter. This portion of adaptive immunity remembers its invaders, it keeps a history. With keeping a memory of the invader, the adaptive immune system already has an antigen created for that specific invader. Whenever the body is re-exposed to this antigen, it will member.The innate immune system is that of which we are born with, It is comprised of the skin, the mucous membranes, and leukocytes and lymphocytes. T and B cells for example. Fevers and Inflammation: Whenever we get a fever or have inflammation, it is our body’s way of telling us that it is trying to fight off a bacteria or virus. Fever and inflammation are achieved through the immune system. It shows the body is working on a line of defense. With inflammation and fever, certain cells are sent to the area of infection to as a defender. Mast cells and macrophages are used in this process.
