Valves
The larger lymphatic vessels are most similar in structure to veins, as they both have valves to prevent backflow and are composed of three layers: tunica intima, tunica media, and tunica adventitia. However, lymphatic vessels have thinner walls and lack a continuous layer of smooth muscle like veins do.
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 flow is primarily controlled by the contraction of surrounding muscles, breathing movements, and the one-way valves in the lymphatic vessels. These valves prevent backflow and help propel lymph towards the heart. Physical activity and massage can also assist in promoting lymph flow.
A lymphoscintigraphy test is commonly used to detect damage or blockage in the lymphatic vessels. This imaging test involves injecting a small amount of radioactive dye into the lymphatic vessels to track the flow of lymphatic fluid. Areas of blockage or damage will show up as abnormal patterns on the scan.
Blood and lymphatic vessels
Skeletal muscles squeeze the lymph through lymph vessels. Valves in the vessels prevent backflow

veins have valves in them that prevent backflow
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.
Lymph moves through the body via muscle contractions, breathing movements, and the contraction of lymphatic vessels. The one-way valves inside the vessels prevent backflow, allowing lymph to flow towards the heart. Movement and physical activity also help to propel lymph through the lymphatic system.
No, there are no valves in the intermammary channels of the breast. The intermammary channels are primarily used for blood and lymphatic vessel passage between the breasts. Valves are typically found in veins to prevent backflow of blood.
a lot of med students call it "fish head"
Lymph moves through the body primarily via the lymphatic system, which consists of lymphatic vessels that transport lymph fluid. Lymph is propelled by the contraction of surrounding skeletal muscles and the rhythmic contraction of lymphatic vessel walls. Additionally, one-way valves within the vessels prevent backflow, ensuring unidirectional flow toward the lymph nodes and eventually into the bloodstream. This movement is further aided by respiratory movements that create pressure changes in the thoracic cavity.

interstitial fluid,lymphatic nodes,lymphatic vessels
Lymphatic vessels originate as blind-ended capillaries in the tissue spaces. These capillaries merge to form larger vessels that eventually join the lymphatic ducts, which return lymph fluid back to the bloodstream.
