The lymphatic system is an important component of the immune system. It includes lymphatic fluid, lymphatic vessels, lymph nodes, spleen, tonsils, adenoids, Peyer patches, and the thymus. Lymphatic fluid consists of an ultrafiltrate of blood collected within lymphatic channels, which run throughout the entire body. The fluid is slow-moving and is transported from the head and extremities to larger vessels, which then drain into the venous system. Along these channels reside approximately 600 lymph nodes.
Lymph nodes are composed of follicles and contain an abundance of lymphocytes. Lymph is filtered through the lymph node sinuses, where particulates and infectious organisms are detected and removed. Because of the exposure to immune challenges, antibody and cell-mediated immunity is mediated. As a result of such normal processes, the lymph nodes can enlarge through either proliferation of normal cells or infiltration by abnormal cells.
Lymphadenopathy is defined as the enlargement of one or more lymph nodes as a result of normal reactive process or a pathologic occurrence. Whereas the (increased) size of the lymph node is the most common reference, an abnormal number or alteration in consistency may suggest a pathologic change that requires investigation and possible intervention.
Clinicians are challenged with the task of differentiating "true" enlarged lymph nodes related to a pathologic process from what are often referred to as "shotty" lymph nodes. "Shotty" lymph nodes refer to small mobile lymph nodes in the neck that are palpable and usually represent a benign change, commonly associated with viral illness.
The removal of lymph nodes to determine the etiology of their enlargement has been practiced for many years, but it is unknown when it was first performed. The removal of lymph nodes is a procedure that is often performed by general adult and pediatric surgeons, as well as by surgical specialists such as otolaryngologists. Because children often presen

When nuclear reactions get going, they spit out particles with enough energy to rip electrons off of atoms or molecules. The altered bonds produce ion pairs that are extremely chemically reactive. This is known as ionizing radiation, and it's where the problems start.
There are many types of ionizing radiation. Take your pick from cosmic, alpha, beta, gamma or X- rays, neutrons, or from a handful more. What really matters is how much an organism is exposed to—a concept called absorbed dose.
One way to measure absorbed dose is in units of Grays (Gy). Another common unit is the sievert (Sv), which takes the Gy measure and multiples it by the type of radiation to calculate the effective dose in living tissue.
