Question

Quizplus · Accepted Answer

Lymph movement is facilitated by several mechanisms: contraction of skeletal muscles helps to pump lymph through the vessels, smooth muscle contractions in the walls of lymph vessels aid in propelling lymph, changes in thoracic pressure during respiration help to draw lymph towards the thoracic region, and external compression of lymphatic vessels (such as from surrounding tissues or organs) can also help to move lymph. All these mechanisms work together to ensure the efficient circulation of lymph throughout the body.
