Final answer:
The method that does not promote or maintain lymphatic flow is a sedentary lifestyle, as movement and muscle contractions are necessary to drive the flow of lymph through the body.
Step-by-step explanation:
The method that is NOT used to promote/maintain lymphatic flow is a sedentary lifestyle. The lymphatic system requires physical activity to move lymph fluid through the body because it does not have a central pump like the heart.
Instead, lymph is moved via the contraction of skeletal muscles and breathing, and is assisted by one-way valves in the lymphatic vessels. Promoting lymph flow can involve massage, exercise, and the use of compression garments. These methods support the movement of lymph towards the heart, where it is eventually returned to the circulatory system.
