Question

Quizplus · Accepted Answer

Lymph fluid is pushed through the lymph vessels by the contractions of skeletal muscles and movements of breathing. This is because the lymphatic vessels do not have their own central pump and rely on external forces to move fluid through the system. The movement of the nearby muscles and respiratory system creates pressure that helps to propel the lymph fluid through the vessels.
