Lymphatic System

Enlarged portacaval lymph nodes are often caused by various underlying conditions, including infections, malignancies, or inflammatory diseases. Common causes include liver diseases such as hepatitis or cirrhosis, as well as cancers like lymphoma or metastasis from other sites. Additionally, conditions leading to portal hypertension can also contribute to lymphadenopathy in this area. Diagnosis typically requires imaging studies and may necessitate further investigation to determine the underlying cause.

One of the major functions of the immune system is to protect the body against harmful pathogens. It also functions to build up a defense system against any potential infections.

Your own cells were created with certain "recognition" proteins on their cell membrane, which tells your immune system to ignore them when encountered. When this process fails, we see many "auto-immune" diseases like multiple sclerosis. It is also recently thought that asthma and diabetes may have some "auto-immune" components which tend to destroy pancreatic islet cells or epithelial cells in the bronchioles.

Lymph travels in lymph vessels. There are varying sizes of lymph vessel, just like with blood vessels. The vessels generally are found just below the skin or in the deeper levels of the skin.

in blood,we have agranular components like lymphocytes,monocytes,macrophages.....these are mainly concerned for our defense system......all these components are much much higher in babies blood.....man has higher number than woman in these componets....that's why babies body temp is much higher than elder one....mother milk contains "colostrum" which helps in producing these componets......but i have no reason,why their count is high in babies.....may be god has made this...........

Phagocytes are very important components of our body's immunity (innate immunity). They are cells that can phagocytose foreign microbes (engulfing microbes by the cell membrane) and then they use enzymes to break down these foreign microbes. Phagocytes may also present the remnants of the microbe to a different type of cells (lymphocytes) to create a memory of that microbe in the body.

Phagocytes eat anything that seems foreign or harmful to the body (bacteria, virus, infected cells) in a process called phagocytosis.

Macrophages are actually a type of phagocyte. They consume large amounts (or clumps) of foreign invaders. They are pretty slow in performing phagocytosis.

Lymphocytes are a type of white blood cell that is found in the blood of vertebrates. There are a few different types of lymphocytes, but the main three are known as T cells, B cells, and NK cells.

Like veins of the blood vascular system, the lymphatic collecting vessels have three tunics and are equipped with valves
Carry lymph. Yea varily.
Lymphatic vessels need a proper method of transport so they can reach their destination. They are not pumped, but pushed along by skeletal muscle contractions, and valves are in place to prevent fluid from flowing backward. They resemble veins, because the vessels need to be small enough to fit within the body along with the other arteries and veins, which are small enough to be in proximity.

Diseases that directly affect the immune system are known as Autoimmune Diseases, including Rheumatoid Arthritis, Multiple Sclerosis, and Chron's disease. Other conditions that impact the body's ability to fight off disease include Diabetes, AIDS, and Hepatitis C.

People with fibromyalgia have low levels of seritonin, so they have a difficult time fighting sicknesses. They also get very little sleep and/or suffer from depression, so that also makes them succeptible to sickness (no energy).

Lymphadenopathy is any disease process involving enlargement of the lymph nodes. This can occur due to infection, autoimmune disease or malignancy.

Lymphoma

A lymphoma is a cancer type which can cause enlargement of lymph nodes so in a way this statement is true as the nodes will enlarge. The lymphoma however is basically a blood malignancy and affects the lymphocyte (a type of white cells). It can therefore produce effects in many different areas of the body of which the lymphatic system ( more specifically the lymph nodes) is only one manifestation.

There are many other things which can have an effect on the lymphatic system including infection, metastases from other malignant tumours, various systemic diseases etc etc etc

I was someone who got sick constantly. I would be down and out for almost a month each year. That's not only no fun physically, but it really hurt me with my job and missing work too. I had a friend who introduced me to a product and said it was especially formulated for strengthening the immune system. It was something completely new...not a vitamin, mineral, herb, or fruit. I was very skeptical at first, but he showed me a ton of scientific studies and so I gave it a try. I've been taking it faithfully for 3 years now and it is incredible! I went 2 years without being sick at all and last year it was for only a couple of days instead a month like in the past. You can find all sorts of information on the product, along with the studies, and even order it at: www.4lifetransferfactorstore.com I highly recommend it. Good luck!

The most common cause of death was infection. Predisposing factors for infection included the underlying disease. Also contributing to death are the following extranadal sites of involvement: respiratory track, bone marrow, liver, kidney and gastrointestinal track.

When donating blood, you do not give enough blood to significantly reduce the number of white blood cells in your system. Those that are lost are quickly replaced in a healthy individual. And individuals with already weakened immune systems are not permitted to give blood.

A liver biopsy can be performed a few different ways: a needle can be inserted through the skin, and take a sample of the liver; during abdominal surgery, a piece of the liver may be removed; through blood vessels, a sample of the liver may be taken. the live sample would then be taken to be studied under a microscope.

Immune system starts rejecting the organ of the recipient because the Human Leukocyte Antigen (HLA) which is present on the surface of the transplanted organ of the donor does not match with the recipient.

Yes. Trust me I am going through it right now.

Immunity is being able to resist a certain disease through preventing develoment of a pathogenic microoranism or by counteracting the effect of it's products.

The lymph nodes store and make B cells which fight antigens (foreign substances in the body).

To elaborate on and attempt to complete the answer, the lymph nodes are where the adaptive immune response begins and is maintained (contrasted with the innate immune response). Dendritic cells circulate throughout the body and pick up antigens (foreign substances in the body, e.g., those of microorganisms such as bacterial cell wall proteoglycans) associated with infected tissue and upon returning to the lymph nodes present them to T and B lymphocytes that pass through or may even reside at the node. The lymphocytes that now recognize the particular antigen proliferate and return to the main circulation and attack the associated microorganism. The adaptive immune response, as by proliferation of antigen specific lymphocytes, is also maintained at the lymph nodes after the infection is gone in case reinfection by the same microorganism occurs.

The two best things you can take to boost your immune system and keep it healthy is Acidophilus (tablets) from your drug store or a health food store. The other is Pomegranate Juice extremely high in antioxidants (the best thing out there.) Buy it pure froma health food section of your grocery store and have 8 ounces every day. Pomegranate juice is thought to have been actually the apple Eve bit into and not an apple. Stay on a well balanced diet with whole grains, proteins (good for the brain)in meats and dairy products (eggs, cheese) eat yogurt, butter is better than margarine, but use it sparingly and Olive Oil is the best oil to use when cooking stir fries, etc. Lots of veggies especially leafy greens such as broccoli, Brussels sprouts as these are good for the colon. Fruits are excellent and many have antitoxidants in them and others are good for digestion and calming the stomach down and also healthy for the colon. Drinking 8 -8ounce glasses water(on a normal day) is a must to flush out kidneys and keep you hydrated and if you are exercising or the weather is hot then drink more water (your body lets you know when you're thirsty.) If you are really thirsty this means your body is already dehydrated.
