Lymphatic and immune systems presentation for chapter 6

  1. 1. By: Michal Peters Bio-120 Presentation 6
  2. 2. <ul><li>“ The lymphatic system is a network of very small vessels . It is used as an extensive drainage network. This drainage network helps to keep bodily fluid level in balance. This drainage network also defends the body against infections that are or will happen. The lymphatic system also helps defend the body against germs like viruses, bacteria, and fungi that can cause sicknesses. Those germs are cleansed out in the lymph nodes.” </li></ul><ul><li>Lymphaticsystem – http://tqnyc.org/2006/NYC063547//lymphaticsystem.html </li></ul>
  3. 3. <ul><li>“ An immune system is a system of biological structures and </li></ul><ul><li>processes within an organism that protects against disease by </li></ul><ul><li>identifying and killing pathogens and tumor cells. It detects a </li></ul><ul><li>wide variety of agents, from viruses to parasitic worms, and </li></ul><ul><li>needs to distinguish them from the organism's own healthy </li></ul><ul><li>cells and tissues in order to function properly . ” </li></ul><ul><li>Immune System – Wikipedia, the free encyclopedia </li></ul>
  4. 4. <ul><li>The following Lymphatic and Immune </li></ul><ul><li>System terms will be discussed in this </li></ul><ul><li>presentation: </li></ul><ul><li>Sarcoidosis </li></ul><ul><li>Hodgkin’s Disease </li></ul><ul><li>Hives </li></ul>
  5. 5. <ul><li>Sarcoidosis is a disease in which inflammation occurs in the lymph nodes, skin, lungs, liver, eyes, or other tissues. </li></ul><ul><li>Patients with sarcoidosis may have no symptoms at all, however, those that do may experience symptoms that include lung and chest symptoms, general discomfort, skin symptoms, nervous system and vision changes, and more. </li></ul><ul><li>The cause of sarcodosis is unknown. </li></ul><ul><li>Sarcoidosis is determined by chest x-ray, CT, blood tests, and possible biopsy. </li></ul><ul><li>More common in African-Americans and females. </li></ul><ul><li>The disease typically begins between the ages of 20-40. </li></ul><ul><li>Symptoms often get better without treatment, however, some patients may require treatment with corticosteroids. </li></ul>
  6. 6. <ul><li>Hodgkin's Disease is a type of lymphoma. </li></ul><ul><li>The cause of this disease is unknown. </li></ul><ul><li>The first sign of Hodgkin's is an enlarged lymph node, but other symptoms include night sweats, fever and chills, weight loss, itchy skin, loss of appetite, and swelling of the lymph nodes in the neck, armpit, or groin. </li></ul><ul><li>Doctors can diagnose Hodgkin’s Disease by a biopsy. </li></ul><ul><li>Treatment includes chemotherapy and radiation but will vary depending on how much the disease has spread. </li></ul>
  7. 7. <ul><li>Hives, also called urticaria, are raised lesions that appear suddenly on the skin (called wheals). </li></ul><ul><li>Hives usually are more or less round in shape and vary in size, up to several inches in diameter. They can appear anywhere on the body, as a single hive or in groups, and may be pink, red, or whitish in color. </li></ul><ul><li>Hives usually are caused by an allergic reaction. However, in some cases, there is no clear cause for the rash. </li></ul><ul><li>There are several triggers that can cause hives including food allergies, chemical allergies, emotional stress, environmental factors, insect bites or stings, medications, etc. </li></ul><ul><li>The most obvious sign of hives is a raised area of skin called a wheal . In some cases, wheals join together and form a large rash that can eventually covers the whole body. Intense itching is another common symptom of hives. </li></ul><ul><li>Eliminating the underlying cause of the hives will usually resolve them. Other over the counter medications including topical creams and ointments and oral antihistamines (i.e.,Benadryl), and corticosteroids. </li></ul>
