Which lymph nodes swell when you have an infection?

Answer 1

they swell and fight the cancerous or disease-causing virus from getting into the body and they also filter foreign matter from the body's fluid.

Answer 2

The lymphnodes swell because they are essentially where all of the dead bacteria and white cells go when the infection is being fought. That is why doctors feel them when you feel sick, for example, strep throat. There are two right below each of your ears, some near your armpits, and others.

Answer 3

Because the lymph nodes contain white blood cells and when they sense bacteria or a virus the release these cells to fight off the infection/virus, thus causing the nodes to swell. If the nodes are tender and easy to move there is nothing to worry about this just means they are fighting of a virus. When they are hard and don't hurt that is when you need to go to the Doctor

Answer 4

When they swell, it's a sign that they're fighting off the infection. Lymph nodes begin to produce plasma cells (type of white blood cell) once a B lymphocyte correctly identifies a foreign antigen. These plasma cells display the same antibodies as the successful B lymphocyte and secrete the antibodies to disable the antigenic particles or organisms. This process is called humoral immunity.
