What structural characteristic ensures a slow flow of lymph through a lymph node?
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

What structural feature of lymphatic vessels is responsible for the forward movement of lymph?
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.
What describes how lymph flows through the lymphatic system?
Skeletal muscles squeeze the lymph through lymph vessels. Valves in the vessels prevent backflow
The method by which lymph is pushed through the lymph vessels is?
The contraction of certain muscles squeezes the lymph vessels, pumping lymph throughout the system
What is difference between serum and lymph?
Serum is in the blood vessels (circulating blood). Lymph is the plasma that diffuses through the arteries (used to be part of the blood) into the lymph system. Once it flows through the lymph system, it will rejoin with blood through veins.
What is lymph node bx?
On it's way lymph passes through masses of tissue called lymph nodes
How does lymph move through the lymph vessels without a pump?
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.
How do hormone reach target cells?
Mainly it is through blood.Some times through lymph
What structure ensures a slow flow of the lymph nodes?
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.
Formation of lymph?
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.
What happens to the lymph after it travels through the lymphatic system?
After it travels through the lymphatic system, the lymph nodes filter lymph, trapping bacteria and other disease-causing microorganisms in the fluid.Lymphatic vessels open into veins and the fluid re-enters the bloodstream.As lymph flows through the lymphatic system, it passes through small knobs of tissue called lymph nodes. Lymph nodes filter the lymph, trapping bacteria and other microorganisms that cause disease. When the body is fighting an infection, the lymph nodes enlarge. If you've ever had "swollen glands" when you've been sick, you've actually had swollen lymph nodes.
Is lymph carried in the cardiovascular system?
Yes, it is both carried through the cardiovascular system, and through the lymphatics. Basically, lymph will first flow through the blood in arteries to the lymph node, then from the lymph node to the lymphatics.
What take place in lymph lodes?
In your blood from your arteries flows into your capillaries. Most of that returns to your heart through your heart. Some returns through the lymph system. The lymph system carries lymph or a fraction of your blood through your system checking for pathogens. It brings them to the lymph nodes. The nodes check the lymph for infection. If the lymph nodes find infection, they start producing antibodies against the infection and inform the rest of the body that infection exist. They sometimes become inflamed when they collect bacteria faster than they can destroy it. Still, they stop it rather than let it go on through the body. They let the lymph go from the lymph nodes back to the veins and back to the heart to recirculate.
