True or false because lymph vessels are very low-pressure conduits, movements of adjacent tissues are important in propelling lymph through the lymphatics.

True

Explanation:

The lymphatic system is a complex network of vessels and small structures called lymph nodes that carry lymph fluid, the lymph, from the tissues back to the circulatory system.

Lymph travels through the lymphatic system due to weak muscle contractions, pulsation of nearby arteries, and movement of the extremities. Lymph depends exclusively on the action of external agents to be able to circulate. The lymph moves slowly and under low pressure mainly due to the compression caused by the movements of the skeletal muscles that presses the fluid through it, in addition the circulation occurs in one direction: towards the heart.
