Lymph Vessels and Nodes of Lung

Lymphatic System (in brief ):

Major structures

lymph vessels
lymph nodes
lymph fluid



Functions of the Lymph System
  • lymph/o
  • drain fluid from tissue spaces and return to it to the blood
  • transport materials (nutrients, hormones and oxygen) to body cells
  • carry away waste products to the blood
  • transport lipids away from digestive system
  • control of infection
  • Lymph originates in blood plasma
  • Interstitial fluid
  • cleans and nourishes body tissues
  • collects cellular debris, bacteria
  • return to blood or lymph capillaries

Lymph Nodes

  • located in lymph vessels
  • small round or oval structures (filters)
  • depositories for cellular debris
  • bacteria and debris phagocytized
  • inside are masses of tissue which contain WBCs (lymphocytes)
  • almost always grouped 2 or 3 to 100
  • invading cells destroyed in nodes and often swell as an indicator of the disease process
