  1. By Cecilia Covarrubias Brandon Quintana Yamilex Rodriguez Period 3 Lymphatic System

  2. What is the Lymphatic System? • Network • Open circuit through the body • Carries lymph • Function: • Defend • Absorbs fat • Transports lymph

  3. Fluid Information • Three types of fluid • Plasma • Tissue fluid • Lymph • White blood cells and lymphocytes • contains proteins and fats • lies in the interstitial spaces of the blood • Protection from foreign particles

  4. Lymphatic Capillaries • Closed- ended tubes extended into interstitial spaces • Receives tissue fluid • Located in the lining of the small intestine

  5. Lymphatic Vessels • Prevents backflow of lymph • Contains three tunics: • tunica interna • tunica media • tunica externa • Carries lymph • Transports fluid away from interstitial spaces in tissues and return it to bloodstream

  6. Lymphatic Ducts and Trunks • Drains lymph from lymphatic vessels • Different types of trunks: • Lumbar Trunk • Intercostals/ Bronchomediastinal Trunk • Intestinal Trunk • Subclavian Trunk • Jugular Trunk • Different Types of Ducts : • Thoracic Duct • Right Lymphatic Duct

  7. Lymph Nodes • Contains blood vessels, nerves, and lymphatic vessels • Filters harmful particles • Contains macrophages • Located in • cervical region • Auxiliary region • supratrochlear region • Abdominal cavity • Pelvic cavity • Thoracic cavity

  8. General Lymph Node

  9. Thymus • Thymus • Made of lymphatic tissue • Adipose and connective tissue replace normal LT • Connective tissue extend inward and subdivide into lobules • T-lymphocytes are matured and leave thymus • Secrete protein hormones

  10. Spleen • Made of connective tissue • Filters • Resembles large lymph node • Fixes damaged blood cells • Contains hilum • Subdivides into lobules

  11. Immune System • Two types: •  Innate Defensive (Non-Specific • Adaptive Defensive (Specific)

  12. Innate Defense (Non-Specific) •  First line of defense against pathogens • Species Resistance • Mechanical Barriers • Chemical Barriers • Natural Killer Cells • Phagocytes • Inflammation/Fever

  13. Adaptive Defense (Specific) • • Immune response with ability to distinguish molecules that are part of the part and those that is not • Second and third line of defense against pathogens • Antigens    -B Cell    -T Cell

  14. Cardiovascular System Vs. Lymphatic System • Team Effort •  Blood • Transportation • Conductive Mediums • Leukocytes vs. Lymphocytes
