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.
1,658 Questions
Do lymphocytes spend little time in the blood?
Lymphocytes recirculate between the lymph and blood; so yes, they do.
What conditions result from excess fluid in the abdomen?
Digestion is hindered; blood flow is slowed. Pressure upward on the chest from fluid-filled organs compromises breathing. The kidneys function poorly in the presence of such external pressures and may even fail.
What are subcentimeter retroperitoneal lymph nodes?
Lymph nodes are bean shaped organs, usually small in size with main function of fighting infection. They are located throughout the body including axilla, inguinal area and peritoneum or abdomen. Retroperitoneal or behind peritoneum- deep within abdomen. Thus retro peritoneal lymph nodes are nodes located deep within the belly (closer to the spine).
What do lymph nodes do Why do they sometimes become large and tender?
Lymph nodes filter out microorganisms and foreign materials that have been taken up by the lymphocytes. When your body fights an infection. lymphocytes fill the lymph nodes.
Is lymph nodes cancer curable?
Most forms are now! This type of cancer is called lymohoma (cancer of the lymph nodes) there are two types. Hodgkins and non-hodgkins. Can be cured by chemo radiation stem cell. Bone marrow transplant. BUT some may not br currable
Can a tick bite cause swollen lymph nodes?
Multiple bites from bed bugs will not cause swolen lymph nodes. However, a small fraction of people bitten will turn out to be allergic to the bite.
E brain. you would not normally expect lymphocytes to cross the blood brain barrier
How does the respiratory system rely on the immune system?
The respiratory system helps you to breathe and if you couldn't breathe correctly your immune system would go down. That is how these system rely on each other.
What effect would the removal of lymph nodes have on the drainage of the pectoral region?
lymphedema in arms, breast, trunk or pectoral region
the third pharyngeal pouch
Where can you find a horse lymphatic system diagram?
A quick search on Google will let you see diagrams of a horse's lymphatic system. You can also find a picture on Horses Inside Out.
Which blood lymph organ filters blood?
The spleens primary function is to filter blood of damaged cells. The spleen is the largest organ of the lymphatic system.
Yes.
What did not get involved in body's immune system?
nothing. Absolutely every part of your body is involved in the immune system. Having said this, not every part CONTRIBUTES to you immune system. I don't think that the muscular system really helps, but every other system does.
Why does ascites return after paracentesis?
Because the reason you got ascites in the first place (liver failure) still exists.
What is mostly likely to happen in a lymph node?
a. attachment of MHC markers to self cells
b. production of B and T lymphocytes
c. phagocytosis of organisms foreign to the body
d. oxygenation of the interstitial fluid
e. destruction of red blood cells and recycling of their contents
How does the immune system respond to a jellyfish sting?
A jelly fish sting would produce an immune response similar to a severe burn or an over reaction/allergy. Inflammation is one of the first responses.
The symptoms are redness, swelling, heat, and pain, which are caused by increased blood flow into tissue. Inflammation is produced by local hormones released by injured cells. These include prostaglandins that produce the dilation of blood vessels and leukotrienes that attract certain white blood cells. These and other chemicals recruit immune cells to the site and promote healing of any damaged tissue.
Contrary to popular belief, you should never urinate on a jellyfish sting. This will just make the problem worse, as does washing the sting with fresh water.
What are two main categories of leukocytes?
The two categories are granulocytes and agranulocytes. Granulocytes have visible cytoplasmic granules. Examples of granulocytes include neutrophils, eosinophils, and basophils. Agranulocytes have no visible cytoplasmic granules. Eamples of agranulocytes include lymphocytes and monocytes.
Where does Lymph drains directly into blood at?
lymph is collected by the thoracic duct and right lymphatic duct and is directly drained into the blood at the right and left subclavian veins
What terms describes and immune system that is inefficient and overactive in the aged?
Inflammaging, straight out of my textbook.
Yes and no from experience... It's not so much the cold that effects the lymph but the effects the blood that helps the flow of lymph. Extreme changes in temp are quite painful for me in that the lymph nodes in my back fill creating pressure on the spine and severe nerve pain. So, yes anything that effects blood flow and breathing effect lymph flow. Try rebounding jumping up and down on a mini tramp. This increases the pressures by as mush as 15X and helps keep things moving.
