Lymph is the fluid carrying the white blood cells. It protects the body against many infections. Lymph nodes are the small areas throughout the body and abundantly present in the neck, arm pits and groin areas. They contain the lymphocytes that fight infections. These nodes filter out harmful organisms and abnormal cells before the lymph reaches the blood. A swollen lymph node is an indication of an infection. It can be a minor infection like the ear infection, strep infection or serious medical problems like the lymphomas, other cancers and AIDS. During pharyngitis which is the inflammation of the pharynx, the lymph nodes swell with the T lymphocytes due to the immune response.

How high can creatinine and bun levels go before death?
wel
Creatinine is a by-product of muscular metabolism. In the natural and normal scheme of things, this substance or waste product can be eliminated from the body. A high-serum creatinine level may cause kidney damage. In relation to the above question as to how high can creatinine levels go before death, it must be noted that kidneys have strong compensatory ability and by that as long as its still 50 percent functional, creatinine level won't be that high. Which leads us to a conclusion that, the lesser the kidney function level is, the higher the creatinine level.

On the other hand for the blood urea nitrogen (BUN) is the most stable blood constituent following death as it reaches antemortem (before death) levels and even after moderate decomposition.

Therefore, as long as the kidneys are functional, regardless of other factors such as the patient's condition/ diagnosis, these blood constituents are nearly normal.
