Bio presentation 4

  1. 1. Lymphatic And Immune system description By Katherine Colon
  2. 2. Phagocytosis <ul><li>Phagocytosis: The process of engulfing or ingesting material. Several types of white blood cells function by engulfing bacteria. A Phagocyte is a neutrophil component of the blood, it has the ability to ingest and destroy bacteria. </li></ul><ul><li>Phagocytosis is a form of endocytosis. </li></ul><ul><li>Phagocytosis begins with the neutrophil or macrophage flowing around the pathogen and engulfing it so that it winds up enclosed in a phagosome (phagocytic vesicle). </li></ul>
  3. 3. Phagocytosis (Continued) <ul><li>Phagocytosis is involved in the acquisition of nutrients for some cells, and, in the immune system, it is a major mechanism used to remove pathogens and cell debris. Bacteria, dead tissue cells, and small mineral particles are all examples of objects that may be phagocytosed. </li></ul>
  4. 4. Hives <ul><li>Hives also know as Urticaria are apart of an allergic reaction they are usually in the appearance of wheals </li></ul><ul><li>Hives usually cause itching, but may also burn or sting. They can appear anywhere on the body, including the face, lips, tongue, throat, or ears. Hives vary in size (from a pencil eraser to a dinner plate), and may join together to form larger areas known as plaques. </li></ul><ul><li>Allergic reactions from chemicals in certain foods, insect stings, sunlight exposure, or medicines can all cause histamine release. Sometimes it's impossible to find out exactly why hives have formed. There are several different types of hives. </li></ul>
  5. 5. Hives (continued) <ul><li>The best treatment for hives is to identify and remove the trigger, Antihistamines are usually prescribed by your doctor to provide relief from symptoms. Antihistamines work best if taken on a regular schedule to prevent hives from forming in the first place. </li></ul>
  6. 6. Sarcoidosis <ul><li>Scardosis is an inflammatory disease of the lymph system in which lesions may appear in the liver,skin,lungs,lymph nodes,spleen,eyes,and small bones of the hands and feet </li></ul><ul><li>No one knows what causes sarcoidosis. The good news is that is it usually temporary. In half the cases, sarcoidosis heals naturally—without any treatment </li></ul><ul><li>It can affect any part of the body but is most common in the lungs—called pulmonary sarcoidosis. In pulmonary sarcoidosis, small patches of inflamed cells can appear on the lungs' small air sacs (alveoli), breathing tubes (bronchioles) or lymph nodes. The lungs can become stiff and may not be able to hold as much air as healthy lungs. </li></ul>
  7. 7. Sarcoidosis (continued) <ul><li>With pulmonary sarcoidosis you may have a dry cough,shortness of breath,mild chest pain </li></ul><ul><li>Any treatment that is needed is focused on relieving symptoms and keeping the lungs and other affected organs working well. The most common treatment for sarcoidosis are drugs called corticosteroids. Corticosteroids work to reduce inflammation in the body. </li></ul>
