Detailed explanation-1: -The lymph glands, or lymph nodes, are small structures that filter the lymph fluid. There are many white blood cells in the lymph nodes to help fight infection. Lymphadenitis occurs when the glands become enlarged by swelling (inflammation), often in response to bacteria, viruses, or fungi.

Detailed explanation-2: -Lymphangitis is defined as an inflammation of the lymphatic channels that occurs as a result of infection at a site distal to the channel. (See Etiology.) The lymphatic system encompasses a network of vessels, glands, and organs located throughout the body.

Detailed explanation-3: -The most common cause of mesenteric lymphadenitis is a viral infection, such as gastroenteritis-often called stomach flu. This infection causes inflammation in the lymph nodes in the thin tissue that attaches your intestine to the back of your abdominal wall (mesentery).
