Basic plan of human lymphatic system

• What is closely connected with the blood circulatory system both structurally and functionally ?

  Lymphatic system
• What are the components of the lymphatic system?

  Lymph vessels

  lymph nodes

  lymphoid tissues (eg: tonsils)

  lymphoid organs (eg: spleen and thymus)
• What are lymph vessels?

  lymph travels through it. Lymph vessels consist of tiny vessels and larger vessels. Tiny lymph vessels are in close contact with the capillaries of the blood circulatory system
• Composition of the lymph nodes?

  Connective tissues and white blood cells
• What is the purpose of the lymphatic system?

  Returns lost fluid and proteins from the blood capillaries back into the blood.
• What is lymph?


  lost fluid from the blood capillaries when they are inside the lymphatic system
• How is the composition of the lymph?


  Same as interstitial fluid
• What does the valves of the lymph vessels do?

  Prevents the back flow of the lymph
• The lymph is drained into what?

  the lymph is drained into the base of the neck via two large ducts
• What helps to move the lymph? 


  The rhythmic contraction of the lymph vessel walls and skeletal muscle movement contraction
• What are the functions of the human lymphatic system?


  Tissue fluid drainage to maintain the blood volume in the blood circulatory system

  absorption of fat and fat soluble vitamins from the small intestine

  for immune responses
