Lymph Circulation is Maintained by All of the Following Except

Question

Lymph circulation is maintained by all of the following except:
A)the heart.
B)inspiration.
C)skeletal muscle contractions.
D)valves.

Accepted Answer

While the heart is responsible for maintaining circulation of blood throughout the body, it is not directly involved in maintaining lymph circulation. The movement of lymph is primarily facilitated by skeletal muscle contractions, the presence of valves to prevent backflow, and the mechanical pressure changes that occur during respiration.
