The lymphatic system has no pump so the flow of lymph is slow. The contraction of surrounding muscles helps to make if flow.
Lymph enters the lymph node through a series of afferent lymphatic vessels and exits the lymph node via efferent lymphatic vessels. There are more afferent lymphatic vessels than there are efferent lymphatic vessels, slowing down the flow. The reason the slow flow is desirable is that it allows time for lymphocytes and macrophages to carry out their protective functions of removing debris from lymph.
The direction of lymph flow is always towards the Thoracic Lymph duct .
The contradiction and relaxation of skeletal muscles moves lymph trough the lymph vessels.
The lymphatic system is composed of assorted size vessels and lymph nodes located throughout the body. There are hundreds of lymph nodes in the body whose function is to filter the lymph fluid. An important part of the body's immune system, lymph fluid contains cells that remove harmful bacteria, viruses and other undesirable substances. The lymphatic fluid system does not have a muscle similar to the heart, which would aid in "pumping" the lymphatic fluid consistently. Therefore, when the lymphatic nodes or vessels become damaged due to surgery, injury or for any other reason, gentle lymphatic drainage massage stimulates the lymphatic fluid flow. Lymph fluid is normally encouraged to flow by the body's natural motion of muscles, organs and other body parts.

The flow of lymph is slow because the lymphatic system has no pump.

each lymph node has fewer efferent than afferent vessels, so the lymph flow stagnates somewhat within the node this is important because it allows time for the generation of an immune response and for the macrophages to remove debris from the lymp before it reenters the blood vascular system
The direction of lymph flow is always towards the Thoracic Lymph duct .
Valves are located in lymphatic vessels and ensure the flow of lymph only goes one way.
Infections
Lymph travels in lymph vessels. There are varying sizes of lymph vessel, just like with blood vessels. The vessels generally are found just below the skin or in the deeper levels of the skin.
Lymphocytes leave and enter lymph node via high endothelial venules. Lymph flow is slow so you have the muscular pump from skeletal muscles and the respiratory pump... similar to venous blood flow.
Lymph nodes
Yes.
Yes and no from experience... It's not so much the cold that effects the lymph but the effects the blood that helps the flow of lymph. Extreme changes in temp are quite painful for me in that the lymph nodes in my back fill creating pressure on the spine and severe nerve pain. So, yes anything that effects blood flow and breathing effect lymph flow. Try rebounding jumping up and down on a mini tramp. This increases the pressures by as mush as 15X and helps keep things moving.
well the flow of lymph fluid is when your ateries are blocked up with flem, green GUNGY flem and it soaks up your insides and overpowers your feaces.
