Yes, swollen lymph nodes are more common than some might think.
Explanation:
The medical terms for swollen lymph nodes are adenopathy or lymphadenopathy.
Lymph nodes play a vital role in fighting off sickness in the body. They act as a filter, trapping bacteria and viruses before they can spread too far.
Lymph nodes <em>typically</em> swell up as a response to bacteria or viruses. Though cancer can be a factor in swelling, it is very rare. Most commonly they are felt right below the corner of the jaw, in the neck. Yet, they are not only in the neck; they are all throughout the body.

<span>The major structure that supplies the cells with nutrients and removes their waste is the circulatory system. The circulatory system is composed of the heart, the blood vessels going from and back to the heart, and the blood that travels inside them. The blood vessels that carry nutrient and oxygen-rich blood to the cells are arteries. They become the thinner arterioles, and then the thinnest capillaries. With the exception of the pulmonary arteries, which carry non-oxygenated blood from the heart to the lungs, all arteries carry oxygenated blood. The capillaries disburse the nutrients and oxygen to the cells and pick up wastes and carbon dioxide, form into the thicker venules, then to form veins, which lead back to the heart (with the exception of the pulmonary veins, which carry oxygenated blood from the lungs to the heart). Veins also differ from arteries in that veins have valves to prevent blood from flowing backward.</span>
