Lymphatic System
This category is for questions about the various vessels by which lymph, a watery fluid of leukocytes, circulates through the body, providing transportation for some materials and removing particulate from tissues.

Do lymph capillaries have valves?
Veins are part of the circulatory system, not the lymphatic system. The two systems are very closely related. Your circulatory systems consists of the arteries which are taking blood from your heart to locations in your body, the veins that are taking blood from locations in your body back to your heart, and the capillaries that interconnect arteries and veins.
How it works is that blood goes from your arteries into capillaries, and then from your capillaries it will go to the different muscles and organs of your body. The fluids from your body tissues will go back into capillaries and then to veins which will take the blood back to the heart where it is re-oxygenated.
The lymphatic system runs very closely with the circulatory system, and is composed of fluid called lymph, rather than blood. Some of the fluids that exit your capillaries are not always taken completely back up into the capillaries at the vein end. This excess fluid goes into the lymphatics and is carried through the lymphatic ducts and nodes. The lymphatic ducts will eventually rejoin the circulatory system at your left subclavian vein. This is the point at which the vein system delivers the blood back to the heart. Lymphatics are important because this is where the majority of your immune cells are located.
What type of Lymph nodes are located along the sides of the neck?
The group of lymph nodes that are located along the sides of the neck are the Cervical Lymph Nodes. There are four that run along side of the neck.
How does the innate immune system interact with the adaptive immune system?
The complement system is a series of about 20 proteins that are involved in a cascade effect during an immune response. Complement is generally divided up into 3 pathways: classical, lectin, alternate. The classical pathway involves a complement protein binding to an antigen-antibody complex (and thus its role in adaptive immunity). Whereas in the alternate pathway, complement (C3) binds directly to the foreign cell( usaully bacteria). Thus its repsonse is non specific and therefore is also part of the innate imune system.
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
Where are a dog's lymph nodes?
They are part of the body's defense system. Not only do they fight both viral and bacterial infections, they also are a very important part of the immune system in that they manufacture antibodies that prevent infections as well.

What are the results of a radical neck dissection?
The mortality rate for radical neck dissection can be as high as 14%. Morbidity rates are somewhat higher and are due to bleeding, post-surgery infection, and medicine errors.
muscular ump lymphatic pump plus the intrestitial pressure
Lymph ducts empty into the circulatory system by draining into the?
Lymphatic vessels drain into the right lymphatic duct. It also drains into the thoracic duct. Lymph moves in response to skeletal muscle contractions.
What is the test that determines the number of differentt types of leukocytes?
Blood smear? Differential count?
What is lymph node in porta hepatis?
enlarged lymph nodes (portahepatis)may be due to:-
1)inflammatory due to chronic cholicystitis.
2)neoplastic (abdominal lymphoma)
3)as a metastasis due to adenocarcinoma of the stomach.
What are the 3 accessory organs of the lymphatic system?
The tonsils, thymus gland, and the spleen are all accessory organs of the lymphatic system.
the leukocyte or white blood cell is located in the immune system or where they may take permanent residence..some tissue.
Does lifting weights hurt your immune system?
To explain this in a very simple way...
When you excercise, you become healthier. This is general knowledge, but many people don't know why.
When you excercise your muscles, your blood circulates better, you burn through fat, and you keep better "physics".
You want to have a good circulation of your blood because it helps keeping your veins (more) clear of bad stuff that isn't suppose to be there. Your organs like your kidneys and liver will be able to work faster and better to cleanse your body of toxins.
This also helps the immune system because you help putting stuff in your body in motion when you excercise. When you excercise you also burn through fat. The body isn't always trying to get rid of fat.
If you put yourself in a scenario of only eating once per day, or once every two days or similar, you put your body in a state of "starvation" which makes the body stock up on fat, leaving less fat for your brain, making you more tired, slow-minded, etc. (in other words, eating to seldom has bad effects on your brain and can affect your personality).
If you excercise, you will feel more hungry more often, and it will help you eat (eat many times per day, but not too much every meal).
Now; burning excessive body fat is important because having too much excessive body fat takes up precious resources to burn through. Remember, you can't burn fat unless you bring the body nutrition (well, you CAN... but it's not very effective if you wanna keep your head straight and stay healthy in general).
Everything is basically linked in the body somehow. Physical activity is good for you because it helps your blood circulate better, your organs work better, which in turn helps your immune system.
Fat is also important. Read about it. Study it.
And think about how fat people are often more sick or have more various problems, since excessive body fat in the end crashes takes up too many resources to handle, which leaves the immune system hanging.
Don't use this in a book or a conversation without reading about it to figure out how it really works... I don't have time to write 200.000 words to explain exactly how it works.
Also, pardon my english.
Why is it important that the lymphatic system is spread throughout the body?
The lymphatic system has tissue spread throughout the body to aid in the removal of fluids from cells, transports fatty acids as well as transporting immune cells to the bones. The lymphatic system is the circulatory mechanism for the immune system.
What mechanisms aid lymph return?
muscular contractions cause movement of lymphatic fluid. Pressure changes in the thoracic cavity during respiration also aid in the movement of lymph.
Elevation of affected area higher than the heart, muscle use, and compression of affected area all increase lymphatic flow.
What happens to the body if your lymphatic system fails?
The lymphatic system returns the fluid that is trapped in the tissues of the body that the capillaries filter. So in essence if we did not have a lymphatic system we would get edema because the tissue would hold in that fluid. That is where elephantiasis comes into play.
The lymphatic system is also the the first line of defense against diseases. This network of vessels and nodes transports and filter lymph fluid containing antibodies and lymphocytes(good) and bacteria (bad).
Lymph vessels are also in then lining of the gastrointestinal tract and they absorb fats from foods. A malfunction can result in serious malnutrition.
