They have valves so that they can move lymphatic fluid much the same as veins by skeletal muscle contraction.

The structure of a lymphatic vessel is most similar to that of a artery?
the walls of lymphatic vessels are similar to those of veins
Is there a system of lymphatic vessels similar to that of blood vessels in the body?
Yes, somewhat. Lymph doesn't circulate like blood but has a system parallel to the blood vessels.
Does heart beat help push lymph along the lymphatic vessels?
yes it does
Does lymph have a pump like a heart?
No the lymphatic system did not have any pump like blood circulation systme. The lymph is moved along the lymphatic vessel network by either intrinsic contractions of the lymphatic vessels or by extrinsic compression of the lymphatic vessels via external tissue forces.
How many valves are found in the heart?
There are four total valves in the heart. The Mitral and Tricuspid in the atria and ventricles The Aortic between the Aorta and left ventricle The Pulmonary between the Pulmonary artery and right ventricle
Which of the following statements is true regarding veins versus lymphatic collecting vessels?
Veins have fewer internal valves than lymphatic vessels.
What structure carries lymph into a lymph node?
Afferent lymphatic vessels
What contained in the lymphatic vessels help prevent the backflow of fluid?
Valves
What structural feature of lymphatic vessels is responsible for the forward movement of lymph?
Valves
What vessels return tissue fluids from interstitial spaces to the circulatory system?
Lymphatic vessels return tissue fluid from interstitial spaces to the circulatory system. Lymphatic vessels are made of thin walls with valves and they carry lymph around the lymphatic system.
What is the relationship between valves in veins and lymphatic capillaries and gravity?
The valves help counter the effect of gravity by preventing the fluid in the vessels from "falling down."
What describes how lymph flows through the lymphatic system?
Skeletal muscles squeeze the lymph through lymph vessels. Valves in the vessels prevent backflow
How do you lymphatic vessels and veins differ in structure?
Lymphatics resemble veins in structure but have thinner walls and more valves.
How does muscular system help the lymphatic system?
Lymph, also known as lymphatic fluid, moves throughout the body in a series of vessels that have one-way valves. As our muscles contract and relax when we move around, the lymphatic fluid moves very slowly through these vessels.
Lymphanges what are they?
Lymphangions are segments of lymphatic vessels that are bounded by valves.
What are located inside the lymph vessels to ensure that the flow of lymph is in the correct direction?
Valves are located in lymphatic vessels and ensure the flow of lymph only goes one way.
How do lymphatic vessels originate?
originates as microscopic blind-end vessels called lymphatic capillaries.
