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.

Which animal has the worst immune system?
Sharks have the best immune systems. Studies show that they resist every disease, even cancer.
Macrophages or phagocytes are inhibited by the increased amound of RBCs in the inflamed area T or F?
I'm pretty sure its false. I have it marked false on my hw and I think i found it in the chapter. Keep googling though just in case.

Should you stop smoking if you had cancer of the lymph node?
You should try to stop smoking no matter what state your health is in.
Are you suppose to be able to feel your lymph nodes in your neck and other places?
No, they are hardly noticable when not swollen. When they are swollen they can be pea-sized or larger.
How many women develop lymphedema after axillary lymph node removal during a mastectomy?
Approximately 10% to 20% of patients develop lymphedema after axillary lymph node removal. however if you get radiation your rate goes up to 50% and good chance of developing lymphedema
What is Glutathione?
Glutathione is your body's master antioxidant. It is a small protein produced naturally in our cells when certain vital elements are present. It functions both as an antioxidant and an antitoxin and is a major defense system against illness and aging.
Our glutathione level actually indicates our state of health and can predict longevity. Although there are more than 60,000 published papers on the beneficial effects of glutathione replacement, it is still largely ignored by mainstream medicine.
In the near future the significance of glutathione will be widely recognized because it has the ability to boost the immune system and fight off the damage of free radicals on the cells.
Modern research has shown that individuals who have low levels of glutathione are susceptible to chronic illness. Decreased levels of glutathione can be brought about by continual stress upon the immune system. As we now know, a lowered immune system can bring about illness and disease. This is a ferocious cycle. While you need glutathione for a productive immune system, a weakened immune system hampers the production of glutathione.
Glutathione has been shown to decelerate down the aging process, detoxify and improve liver function, strengthen the immune system, and reduce the chances of developing cancer. Glutathione also works to help improve mental functions, increase energy, improve concentration, permit increased exercise, and improve heart and lung function - just to name a few.
As we age, and expose our bodies to stress, chemicals, pollutants, and average lifestyle habits, we begin to lose energy, vitality, mental alertness, and more. Most of us are aware that there are consequences for our actions; however the danger lies in the fallacy of believing that you will start taking better care of yourself tomorrow.
Dr. Robert H. Keller, one of the worlds leading scientists, dedicated 10 years of research and development in creating MaxGXL to assist the world in its quest for a higher level of health.
Out of all the biological processes that Dr. Keller could have focused his attention on, he chose to investigate a way to naturally optimize the bodys production of glutathione. Glutathione may not be well-known outside of medical circles, but your body relies on its function every single day.
Discover how to strengthen your immune system to fight off diseases and illnesses like: Lupus, Cancer, Alzheimers, Fibromyalgia, Gout, Multiple Sclerosis, Rheumatoid Arthritis and Many more.

How can the lymphatic circulation become clogged?
The lymphatic circulation may become clogged by infection, injury, or several other types of cancer that have spread through lymphatic channels. Swelling, sometimes massive, can result from blocked lymphatics.
Lymph and mechanisms of lymph transport?
Lymph is a tissue that diffuses into the lymphatic capillaries
Is fever an immune system response?
From what I know, yes, a fever is a result of the immune system's response to a medical condition that a person may have. In some cases it could be something very minor such as the flu, various skin inflammations like boils, infections such as malaria, cancers, and many more things. This is because of Hypothalamus, aka the bodies immediate nerve responses (from the brain) to these infections and diseases that are now in the body. This response is brought on by the body in order to combat the loss of heat that the body may have due to vasoconstriction (narrowing of arteries/veins), and the bodies over compensations due to the invading substance/disease/infection (whatever you want to call it.
What is the action of the lymphatic system?
The lymphatic system has two major functions. One is carry white blood cells to where they they may be needed and second to bring back excess fluid from the body tissues to the blood.
What can a mediastinoscopy show about the lymph nodes of a lung cancer patient?
The lymph nodes in the mediastinum are likely to show if lung cancer has spread beyond the lungs.
the microbe of tuberculosis enters the lungs and the body responds by sealing it off inside nodules or tubercles
At a basic level here's how it works: The surfaces of our cells have protein "markers" embedded in them, each person's markers are unique. If the immune system doesn't recognize the markers on a cell, it will attack it as being foreign. This usually works pretty well asa defense systems go, however, there are times (autoimmune diseases like Grave's disease, MS and rheumitoid arthritis) when the system attacks the body's own cells anyway or other diseases (HIV, etc) where the immune system doesn't recognize foreign cells, so doesn't attack.
Where in your body are there bacteria that does not get attacked by the immune system?
E.coli in Intestine
Yes, any cell that has membrane bound organelles is eukaryotic.
Do T lymphocytes stimulate B lymphocyte production?
Specific response - 2 main types (cell mediated and antibody mediated immunity) may accompany or follow non specific reactions e.g. inflamation, but both rely on the actions of B and T lyphocytes. B cells make protein antibodies (gammaglobulins) that react against foreign proteins (antigens). T cells multiply and attack the pathogen.
Cell Mediated Immunity - once a T cell recognises an antigen it multiplies rapidly. Helper T cells activate B cells to make antibodies, macrophages engulf the microbes along with any debris. Killer T cells attack the microbes and any infected body cells using strong powerful proteins (lymphokines). Suppressor T cells inhibit the response of other cells to the invading nicrobes.
What lymphocyte is the main signaling cell in adaptive immunity?
Dendritic cells. They will take in pathogens and present them on MHC's (class 1 or class 2) depending on the nature of the pathogen. Dendritic cells will travel to your secondary lymph system (lymph nodes) for the pathogen to be identified and appropriately responded to.
Valves are located in lymphatic vessels and ensure the flow of lymph only goes one way.
Thorasic lymph duct starts from?
The thoracic duct is the major lymphatic vessel, which starts near the lower part of the spine. It collects lymph from the lower portion of the body.
