(lymph passes through lymph nodes along the way)

4

3

5

What are the 3 topics for the mechanisms for the movement of lymph?

skeletal muscle contractions
changes in pressure
smooth muscle contractions

6

Mechanisms for the movement of lymph:
What happens when the skeletal muscle contracts?

it milks the collecting lymphatic vessels

7

Mechanisms for the movement of lymph:
What happens when the pressure changes?

changes in pressure during inhalation and exhalation (respiratory pump)

8

Mechanisms for the movement of lymph:
What happens when the smooth muscle contracts?

smooth muscle in the lymphatic vessels reflexively contracts when the vessel is filled with fluid

9

Mechanisms for the movement of lymph:
Where does the smooth muscle contract and when?

in the lymphatic vessels
when the vessel is filled with fluid
