Presentation of lymphatic and immune systems

  1. 1. Presentation of Lymphatic and Immune Systems<br />Cassandra Fox<br />June 23, 2010<br />Chapter 6<br />
  2. 2. Lymphatic and Immune Systems<br />The lymphatic system is made up of lymphatic vessels, lymphatic nodes, the spleen, tonsils and the thymus gland.<br />The Immune system is our bodies first line of defense against disease. <br />Together with the Hematic system they<br /> protect the body by locating and killing<br /> our own diseased cells, invading pathogens <br /> and harmful substances.<br />
  3. 3. Diseases of the Lymphatic and Immune system<br />Elephantiasis<br />Human immunodeficiency virus HIV<br />Acquired immunodeficiency syndrome AIDS<br />Kaposi’s sarcoma<br />
  4. 4. Elephantiasis<br />Elephantiasis is a parasitic disease that causes severe inflammation, by obstruction of lymph flow. <br />It is mostly contracted by Mosquito's. They carry the worm which enters your body once the mosquito bites you and ends up in the lymph vessels.<br />A less common form of elephantiasis is caused by the streptococcus bacterium.<br />There are three options for treatment Pneumatic pumps, Surgery of some kind or Complete Decongestive Physiotherapy.  <br />This disease is only curable in its early stage. Once the limb becomes permanently enlarged, there is no cure.<br />
  5. 5. Human immunodeficiency virus HIV<br />HIV is the virus that causes AIDS. <br />HIV progressively destroys your body's ability to fight infections and certain cancers. <br />Symptoms of HIV usually is an acute illness with nonspecific or flu-like symptoms such as fatigue, headache, fever, and enlarged lymph nodes.<br />HIV infects immune cells called CD4 T-cells and slowly begins to decrease their numbers. <br />The infected person’s immune system responds to the acute HIV infection by producing antibodies against the virus. In most people, the initial symptoms go away after a short time period. <br />Even when the antibodies seem to be working and the person feels better, the virus is still destroying their CD4-T cells and will eventually compromise their immune system.<br />
  6. 6. Acquired immunodeficiency syndrome AIDS<br />AIDS is a disease caused by the human immunodeficiency virus, HIV. HIV damages the immune system by attacking lymphocytes. <br />Once the lymphocytes are destroyed, the body is less protected from viruses, it can’t fight infections and becomes vulnerable.<br />AIDS is passed from person to person through contact with blood or bodily fluids.<br />Due to the weakening of the immune system in AIDS can lead to unusual cancers like Kaposi’s sarcoma.<br />There is no known cure for HIV/AIDS. There are only medications to help slow its progression and help prevent or cure some of the illnesses that come with AIDS. <br />Medications that fight HIV are called anti-retroviral medications. Highly active anti-retroviral therapy HAART is a treatment that must be continued for life. It is not a cure.<br />
  7. 7. Images of HIV and AIDS<br />
  8. 8. Types of Kaposi sarcoma <br />Epidemic (AIDS-related) Kaposi sarcoma develops in people who are infected with HIV.<br />Classic (Mediterranean) Kaposi sarcoma occurs in elderly people of Mediterranean, Eastern European, and Middle Eastern heritage.<br />Endemic (African) Kaposi sarcoma occurs in people living in Equatorial Africa and is sometimes called African KS.<br />Iatrogenic (transplant-associated) Kaposi sarcoma develops in people whose immune systems have been suppressed after an organ transplant.<br />
  9. 9. Kaposi sarcoma <br />Kaposi's sarcoma is a form of skin cancer that causes lesions of abnormal tissue to grow that metastasize to internal organs.<br />KS can cause different problems depending on the area it infects. KS in the digestive tract, can cause bleeding, while tumors in the lungs may cause difficulty breathing.<br />Radiation treatment is used to help lesions that are painful, bleed, cosmetically disturbing, largely infect the mouth, protrude through the skin or block lymphatic's. <br />There are no symptoms to detect KS in its early stages. Once it has reached the epidemic form it may be the first sign of AIDS. <br />
