1 The Lymphatic System Arinze,Lilianna,Drew,Kaelyn

 The functions of the Lymphatic System  Where lymph comes from  The role of lymph organs  About lymph nodes  Lymphatic disease  Results of lymphatic system failure What You’ll Learn!

 Dissolved substances become part of fluid tissue  Helps defend diseases Purpose of Lymphatic system

 Lymphatic System: collects fluid from body tissue spaces,and returns it to the blood through lymph capillaries and lymph vessels;plays a vital role in protecting against infection.  Lymph: tissue fluid that has moved around cells,and into lymph vessels; consists mostly of water,dissolved substances,and lymphocytes.  Lymphocyte: type of white blood cell produced by the lymphatic system that fights infections,and foreign materials that enter the body.It’s located in the bone marrow. Glossary

 Lymph nodes: bean-shaped structures found throughout the body that filter out microorganisms,and foreign materials that enter the body.  Biopsy: a medical test involving the removal of cells and tissues. Glosssary part 2

 Tonsils and spleen  Thymus gland  Thoracic duct  Bone marrow Lymphatic organs Lymphatic organs

 Filter out microorganisms and foreign materials  Bean shaped structure  Help fight infections  In the organ of the immune system  Can be diagnosed by a biopsy  Can be fatal Lymph nodes

 HIV  With fewer T cells, less able to fight  Death risk  Cold can be serious Disease of Lymphatic System

 Acts like your personal security guards  Does not allow invasion  Helps protect against diseases. Why it’s imporant.
