The Lymphatic and Immune System

  1. 1. The Lymphatic & Immune System<br />Linda Khauv<br />Biology 120 WW2<br />
  2. 2. Lymphatic and Immune System<br />Lymphatic System<br />Consists of organs and lymph nodes<br />Lymph fluids distributes immune cells and interacts with the circulatory blood system to drain fluid from cells and tissues<br />Has immune cells that protect the body against viruses and bacteria<br />Immune System<br />Consists of special cells, proteins, tissues, and organs<br />Fights against germs and bacteria <br />Preventing infections<br />
  3. 3. Allergy<br />Allergy is the body’s reaction of the immune system when in contact with a foreign system<br />Not everybody is allergic to the same substance<br />Allergy (Allergen-producing) substances may include:<br />Dust mites<br />Pollens<br />Certain foods<br />Medications<br />
  4. 4. Allergy Reactions and Causes<br />Reactions usually occur at the: <br />Eyes<br />Nose<br />Lungs<br />Skin<br />Stomach<br />Allergic reactions and causes may differ for different people. It also depends on what they are allergic to.<br />Symptoms for the allergic reaction varies.<br />
  5. 5. Allergic Reactions<br />Some allergic reactions and its symptoms are:<br />Allergic Rhinitis: Runny, stuffy or itching of the nose, and itchy ears and throat<br />Asthma: Shortness of breathe, coughing, wheezing and chest tightness<br />Allergic Eyes: Watery, redness, or itchy eyes, Swelling of the membranes<br />Allergic Eczema: Itching, redness or dry skin, face, eyes, elbow rashes and or rashes behind the knee or trunk of the body<br />Hives: Raised red welts and intense itching<br />The most severe reaction: <br />Allergic Shock: Hives or reddish discoloration of the skin, Nasal congestion, Swelling of the throat, nausea, vomiting, stomach pain, shortness of breath, wheezing, low blood pressure and or shock<br />
  6. 6. Raised itchy welts on the skin’s surface<br />This is an allergic reaction from food or medication. <br />
  7. 7. Allergic Reaction Treatments<br />Medications<br />Antihistamine medications<br />Benadryl <br />Claritan<br />Hydrocortisone Cream for inflammation of the skin or rashes<br />Cold wet cloth or ice for small reactions<br />Nasal corticosteroid sprays <br />Epinephrine<br />Corticosteroids<br />Allergy shots<br />Severe reactions<br />Oxygen therapy for breathing difficulties<br />Intravenous fluids to boost blood pressure from Anaphylactic shock<br />Hospitalization<br />
  8. 8. Hodgkin’s Disease<br />It is Cancer of the Lymphatic System which is part of the immune system<br />There are cells that may grow abnormally and can spread in the Lymphatic System making it harder for the body to fight infections<br />There are two types:<br />Hodgkin's lymphoma<br />Non-Hodgkin’s lymphoma<br />
  9. 9. Signs and Symptoms<br />Hodgkin’s symptoms may include:<br />Painless swelling of lymph nodes<br />Fatigue<br />Fever<br />Chills<br />Night sweats<br />Weight Loss<br />Coughing <br />Trouble breathing/chest pain<br />Loss of appetite<br />Itching<br />

Hodgkin’s Disease Treatment<br />Treatment depends on :<br />Treatment may include:<br />The lymph nodes affected<br />Stage of disease<br />If both sides of your diaphragm are involved <br />Your age<br />Symptoms<br />If you’re pregnant<br />Overall health status<br />Chemotherapy<br />Radiation<br />Bone Marrow Transplant<br />Stem Cell Transplant<br />
  12. 12. Sarcoidosis<br />Sarcoidosis is an inflammatory disease of the lymph system where lesions may appear at the site of liver, skin, lungs, eyes, lymph nodes, and small bones of the hands and feet<br />It may come from abnormal immune system response and may be from something airborne<br />
  13. 13. Sarcoidosis Symptoms<br />Systems vary depending on organ affected and length of time the disease have been in your system<br />Symptoms may include:<br />Fatigue<br />Fever<br />Swollen lymph nodes<br />Weight loss<br />Dry cough<br />Shortness of breath<br />Wheezing<br />Chest pain<br />Rash<br />Lesions<br />Skin discoloration<br />Blurred vision<br />Eye pain or redness<br />
  14. 14. Sarciodosis<br />Above picture shows Sarciodosis of the skin.<br />
  15. 15. Sarcoidosis Treatment<br />Sarcoidosis may disappear itself depending on its severity. Treatment is only needed if it is threatening to an organ<br />Medication treatment:<br />Corticosteroids: an anti-inflammatory drug<br />Anti-rejection drugs: reduce inflammation by suppressing immune system<br />Anti-malarial drugs: helpful for skin disease, nervous system, and high blood-calcium levels<br />TNF-alpha inhibitors: treat inflammation<br />Surgery:<br />Organ transplant for severely damaged liver or lungs<br />
