GENERAL HISTOLOGY

Detailed explanation-1: -Swollen lymph nodes usually occur as a result of infection from bacteria or viruses. Rarely, swollen lymph nodes are caused by cancer. Your lymph nodes, also called lymph glands, play a vital role in your body’s ability to fight off infections.

Detailed explanation-2: -They last for longer than two weeks – Swollen glands caused by an infection will normally go down within two or three weeks (i.e until the infection has been naturally dealt with). Make sure you visit your GP if your lymph nodes don’t seem to be improving within this time or aren’t getting better with antibiotics.

Detailed explanation-3: -Bacteria (or their products) picked up from the tissues by cells called macrophages, or those that flow into the lymph, are forced to percolate through the lymph nodes. There, white blood cells called lymphocytes can attack and kill the bacteria.

Detailed explanation-4: -Swollen lymph glands are usually a sign of infection and tend to go down when you recover. However, they can sometimes have a more serious cause and may need to be seen by a doctor. Lymph glands (also called lymph nodes) are pea-sized lumps of tissue that contain white blood cells.
