They start as lymphatic
capillaries, that merge to form larger
vessels, that empty into veins in the
thoracic cavity

Obtained through antigen exposure, long lasting immunity.

drain lymph from the lymphatic vessels

Contain lymphocytes and
macrophages, are located in groups or chains
along lymphatic vessels

protection

3 layers

Obtained by receiving antigen, short term immunity.

tissue fluid that has entered a lymphatic capillary;
lymph formation depends on tissue fluid formation

Remove bacteria and cellular debris before
lymph is returned to the blood

lymph

Collect and carry away excess fluid from
interstitial spaces

Occurs after exposure to the antigen itself, due to primary immune response.

Drives the entry of
fluid into lymphatic capillaries

Monitor body fluids; performed by
lymphocytes and macrophages

toxin

Organs, cells, and biochemicals of the lymphatic system

Involves the injection of
gamma globulins containing antibodies or antiserum

A condition that interferes with the flow in lymph will result in an accumulation of lymph in the interstitial spaces.

Attack viruses, bacteria and parasitic cells that
enter a lymph node

again

Absorbed fats

Through natural events, such as getting
a disease, or induced artificially, by an injection

Diffuse, unencapsulated lymphatic tissue associated with the digestive, respiratory, urinary, and reproductive systems

Engulf and destroy foreign particles, debris,
and damaged cells
