Lymphatic System (continued)

• The lymphatics are joined together by lymph nodes which act as filters and empty into the right lymphatic duct or the thoracic duct

• Lymphatics:

  • smaller diameter and thinner walls than veins or arteries
  • contain valves like veins to assist with lymph flow
  • also are aided by skeletal muscle contractions and pulsatile movements of surrounding blood vessels to assist with lymph flow
