Lymphatic System Research Paper
The lymphatic system is not a close system and the movement of the lymph fluid moves with low pressure due to functions such as peristalsis, valves, and the milking action of skeletal muscles. Lymph fluid only ever travels in one direction.
As the lymph fluid moves through the body, it collects waste products and toxins and disposes of them through the bladder, bowel, lungs, and skin. The lymphatic system also takes part in returning plasma proteins to the bloodstream. The antibodies which are made in the lymph nodes help the body to build an effective immunity to infectious diseases. The lymph nodes are involved in defending mechanisms of the body by removing bacteria and toxins. Lymph nodes are very small organs that you can find within the body; they are the site of filtration of the lymph fluid and also activate

Antibodies and immune cells in the tonsils help to kill germs and help to prevent throat and lung infection
Adenoids - Like tonsils, adenoids help to defend the body from infection. They trap bacteria and viruses which you breathe in through your nose. They contain cells and antibodies of the immune system to help prevent throat and lung infections.
Thymus - The gland releases a hormone that stimulates the production of a certain type of white blood cell in the bone marrow; these cells, called thymocytes are transported by the bloodstream to the thymus. There, the organ programs the cells to attack antigens that invade the body and to not attack normal cells in the body itself. Once matured, these T lymphocytes, or T cells, circulate through the bloodstream and collect in the lymph organs, the spleen and lymph nodes, for future use.
Lymph nodes - Lymph nodes act as filters or traps for foreign particles and are important in the proper functioning of the immune system. They are packed tightly with the white blood cells called lymphocytes and

    What are the thymus gland functions? The thymus functions chiefly to develop T lymphocytes. Once mature, these cells leave the thymus and are transported via blood vessels to the lymph nodes and spleen. T-lymphocytes are responsible for cell mediated immunity, which is an immune response that involves the activation of certain immune cells to fight infection.…

    Lymphoid tissue is located in many organs, especially the lymph nodes and in the lymphoid follicles such as the tonsils. Lymphoid tissues consist of lymphocytes and other types of cells for support in case of disease. The lymphatic system also included specialized structures for the production of lymphocytes and also for circulation. Lymph nodes produce the white blood cells that are more commonly known as lymphocytes. These are formed by the thymus, bone marrow and spleen. The first type of lymphocyte is the ones that attach to invading microbes. They do this directly whilst others make antibodies that circulate in the blood and attack microbes. When micro-organisms attack the body, antigens are transported to the lymph. The lymph is then carried through the lymph vessels to different regional lymph nodes. The lymph nodes contain macrophages and dendritic cells ingest the antigens, process them and show the antigens to lymphocytes. They can then start making antibodies or serve as memory cells. Memory cells are used to recognize particular antigens in the future, in time of disease especially. The lymphatic system can therefore be used as transport and defence. It is essential to return the fluid and proteins that have got out through blood capillaries into the blood system and it is also in charge of picking up products of fat digestion in the small…

    The lymphatic system serves as a conduit for trafficking of lymphocytes and antigen-presenting cells to regional lymph nodes, where the immune system encounters pathogens, microbes, and other immune elicitors. Microorganisms and other foreign substances are filtered from lymph by lymph nodes and from blood by the spleen. In addition, lymphocytes and other cells are capable of destroying microorganisms and other foreign substances. Because the lymphatic system fights infections, and filters blood and lymph to remove microorganisms, many infectious diseases produce symptoms associated with the lymphatic…

    The Immune system is one of the most important parts of the human body. Its role is to protect us from outside dangers such as pathogens and disease and to keep the body healthy. The immune system protects the body from disease by having a complex system of organs and cells to keep the body safe. The first barrier of the immune system and of the body is the skin which keeps out pathogens from entering the body, but if there is a cut in the body, the skin can no longer defend against the pathogen, so next comes inflammation which helps to limit the spread of the disease by causing swelling and a large amount of white blood cells to go to the injured parts of the body. Another really important…

    Both lobes of the thymus consist of many smaller sections called lobules. The lobules consist of and inner and outer layer. The inner layer is called the medulla and this is made of mainly T- cells and epithelial cells. The outer layer is called the cortex and this is again made of T-cells but these cells are developing which means the T-cells mature and once matured, they clone themselves producing specialised T-cells. The maturation and development of all the T-cells happens within the medulla. The diagram above shows the structure and position of the…
