Lymph transport involves all of the following EXCEPT ________.
A) lymph capillary minivalve action
B) milking action of active muscle fibers
C) thorax pressure changes during breathing
D) smooth muscle contraction in the lymph capillary walls

Question

Quizplus · Accepted Answer

Smooth muscle contraction is not involved in lymph transport. Rather, lymph flow is dependent on the surrounding muscle contractions and pressure changes. Lymph capillary minivalve action allows for fluid to enter the capillaries but prevents it from exiting, while the milking action of active muscle fibers and thorax pressure changes during breathing help to propel lymph through the vessels.
