10. The structure of the
Lymphatics
Structure Function
Lymph Fluid Transports excess fluids, waste
and lymphocyte cells around
the body
Lymph
Capillaries
Drain away excess fluid & waste
products from the tissue
spaces in the body
Lymph Vessels Carry the lymph towards the
heart. Once lymph has passed
through the vessels it drains
into the lymph node

11. Lymph Nodes Acts as a filter of lymph to
remove or trap any micro-organisms,
cell debris or
harmful substances

3. Transports proteins back into the blood
supply.
4. Produces lymphocytes which protect and
