The lymph is circulated via muscle movement. The lymphatic system is not closed and has no central pump; thus transport is slow and sporadic. Lymph movement occurs due to peristalsis (propulsion of the lymph due to alternate contraction and relaxation of smooth muscle), valves, and compression during contraction of adjacent skeletal muscle and arterial pulsation.

i think its the pulmonary vein, aorta, and main artery
What is the direction of centripetal force?
Toward the center of curvature of the path along which it causes the object to move.

The contradiction and relaxation of skeletal muscles moves lymph trough the lymph vessels.
What functional group in the DNA structure causes it to move only toward the positive poles?
The negatively charged phosphate groups of the DNA causes them to move only towards the positive poles
Which organ causes a pulse?
The heart beating ie. pushing blood around the body. Each pulse is a heart beat, which causes more pressure as it puts pressure behind the blood to move it.
Reason for elevating the legs when are swelling from acute Brochitis?
To help move the blood back toward the heart
Does the squeezing of skeletal muscles move lymph through the lymphatic system?
Yes. The lymphatic system does not have a "heart" like in the circulatory system to pump its contents around, so it relies on the movement of adjacent muscles and vessels to propel lymph.
What are the blood vessels that direct blood toward the heart?
Veins move blood back to the heart. Think of the "V" as part of an arrow and the arrow is shooting the blood BACK to the heart.
