The contraction of certain muscles squeezes the lymph vessels, pumping lymph throughout the system
Skeletal muscles squeeze the lymph through lymph vessels. Valves in the vessels prevent backflow
Lymph is moved through the lymph vessels by surrounding muscles contracting and relaxing, which creates pressure changes that help propel the lymph forward. Additionally, one-way valves within the lymph vessels prevent the backflow of lymph, helping to maintain the flow.
The lymph nodes are the only lymphatic organ with afferent vessels. Afferent vessels carry lymph fluid into the lymph nodes, where it is filtered and processed before being returned to circulation through efferent vessels.
A lymph vessel. They are similar in function to blood vessels. However the lymph is moved along the vessel by muscle contractions rather than by the heart pumping.
The vessels through which lymph finally rejoins the general circulation are called lymphatic ducts or lymphatic vessels. These ducts empty lymph into the bloodstream near the neck.
Lymph nodes have efferent lymphatic vessels that drain lymph away from the node. These vessels carry filtered lymph containing immune cells and waste products back into the bloodstream.
Lymph is formed when interstitial fluid and proteins from the tissues enter lymphatic vessels through lymph capillaries. This fluid is then transported through lymphatic vessels and filtered through lymph nodes before ultimately re-entering the blood circulation through the thoracic duct or right lymphatic duct.
Afferent lymphatic vessels bring lymph into a lymph node. These vessels help transport lymph, which contains immune cells and waste products, into the node for filtering and processing.

One-way valves inside the lymphatic vessels prevent the backflow of lymph, helping to maintain a unidirectional flow towards the heart. This structural design ensures that lymph is pushed in the right direction, from the tissues towards the bloodstream.
Lymph is transported in the body primarily through the lymphatic system, which consists of a network of lymphatic vessels that run parallel to the blood vessels. Lymph is collected from tissues and is carried through these vessels toward the lymph nodes, where it is filtered. The movement of lymph is facilitated by the contraction of surrounding muscles and the presence of one-way valves that prevent backflow. Ultimately, lymph is returned to the bloodstream via the thoracic duct and the right lymphatic duct.
