Comparison between Lymph Vessels and Veins.
- Similarities.
- both have an interconnecting network of progressively larger vessels;
- both transport fluids to the heart;
- the larger lymph vessels have the same structure as veins, i.e. their walls have the same three layers;
- both have semi-lunar valves to prevent any backward flow of blood;
- the flow of fluid is slow but steady and at low pressure;
- the fluid is deoxygenated;
- like blood capillaries, the walls of lymph capillaries are composed of a single thin layer of squamous endothelium.
- Differences.
- the walls of lymph vessels are musch thinner and more transparent;
- the muscle layer in lymph vessel is much less developed, but there is more connective tissue;
- blood capillaries form a continuous, open circuit, whereas lymph capillaries end blindly in the tissues;
- lymph capillaries have a larger diameter than blood capillaries;
- lymph capillaries have walls which are more permeable than the walls of blood capillaries. Consequently, larger molecules (such as proteins) are able to diffuse through them.

∙ 13y agoThe Lymphatic collecting vessels have the same three tunics as veins, but the collecting vessels are thinner walled, have MORE internal valves than veins, and anastomose more.

Which of the following statements is true regarding veins versus lymphatic collecting vessels?
Veins have fewer internal valves than lymphatic vessels.
What is the name of the vessels that carry lymph from the lymphatic to the veins?
collecting vessels
The veins that receive lymph from the two terminal lymphatic vessels are the?
Subclavian veins
Vessels in the lymphatic system?
The lymphatic System- Consists of lymphatic vessels i.e. Veins and capillaries are an example. (hope this helps and I had the exact question in a worksheet and it was right good luck)
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
What important vessels enter or exit the lung at its hilum?
the pulmonary artery, pulmonary veins, bronchial vessels and lymphatic vessels
What is the name of the vessel that carry lymph from the lymphatic capillaries to the veins?
collecting vessels
How do you lymphatic vessels and veins differ in structure?
Lymphatics resemble veins in structure but have thinner walls and more valves.
Why do lymphatic vessels have valves?
They have valves so that they can move lymphatic fluid much the same as veins by skeletal muscle contraction.
What do collecting lymphatic vessels NOT share in common with veins of the cardiovascular system?
Thickness of the walls.
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."
Trace the sequence of fluid flow through blood vessel to blood vessel by way of the lymphatic system?
The sequence of fluid flow is blood capillaries.... interstitial space or interstitial fluid..... lymphatic capillaries.... lymphatic vessels.... lymphatic ducts..... junction of the internal jugular and subclavian veins. Then what helps this whole sequence is the skeletal muscle pump and the respiratory pump.
