What do the lymphacytes and macrophages of the lymphnodes due?

Back 21

clean the lymp0h as it flows throu the node.

Front 22

What do the white blood cells within lymph do

Back 22

filter lymph and remove bacteria and cellular debris before it returns to the blood

Back 27

Blood

Front 28

What does the spleen do?

Back 28

filters the blood and removes damaged blood cells and bacteria

Front 30

What would happen with out a lymphatic system?

Back 30

fluid would accumulate in tissue spaces

Front 31

Walls of the lymphatic capillaries are

Functions of lymph nodes include

Back 39

filtering foreign substances from lymph immune surveillance
