Original Question
ctivity 26.5 Case Study: Lymphadenopathy This activity targets LO 26.6. Jordan wakes up the morning of an important exam and isn’t feeling well. It hurts to swallow and the muscles in their arms and legs feel sore. They decide to tough it out and take their test, but by the end of the day they feel worse, and they have a significant swelling on either side of their neck. The next day, Jordan goes to the campus health clinic. The nurse examines Jordan and feels the swelling on the sides of their neck. “You have swollen cervical lymph nodes,” says the nurse. The nurse suspects that Jordan may have strep throat or infectious mononucleosis (mono). Both infections can present with a sore throat, achy body, and swollen lymph nodes. The nurse notices some swelling in Jordan’s tonsils and swabs the back of Jordan’s throat to send off to the lab. The results come back positive for group A Streptococcus (group A strep throat). Jordan’s nurse prescribes a round of antibiotics to help Jordan fight off the infection. 1. Assuming that Jordan is infected with a pathogen, why have the lymph nodes swelled? The immune system cells of Jordan’s body are dividing to make more immune cells to fight the pathogen, as their numbers increase the nodes get larger. Lymphatic fluid is arriving in the nodes and not moving forward. As more fluid arrives the nodes get larger. The pathogen is getting caught in the nodes, as more gathers there the nodes get larger. Assessment question 2. Considering the location of the swollen lymph nodes, which location in the body most likely is infected with pathogens? Arms Throat Lungs Assessment question 3. The lymphatic fluid leaving the cervical lymph nodes will flow through lymphatic vessels. These lymphatic vessels will then join to form which trunk? Bronchomediastinal trunk Jugular trunk Subclavian trunk Assessment question 4. Jordan’s cervical lymph nodes are swollen on both sides of their neck. The lymph leaving these nodes will eventually be returned to the blood at what location(s)? From the right lymphatic duct into the right subclavian vein From the thoracic duct into the left subclavian vein Both of these Assessment question 5. Which tonsils, shown here, was the nurse able to see in Jordan’s throat? Pharyngeal tonsils Lingual tonsils Palatine tonsils Assessment question 6. Jordan’s tonsils are swollen because the Streptococcus bacteria are growing there. How did the bacteria get there? Jordan picked up the bacteria in a cut, and the bacteria used the blood to travel to the tonsils. Jordan inhaled some air that contained the bacteria, and the bacteria were caught in the tonsillar crypts. The bacteria were in the tissues of Jordan’s head and neck, and the bacteria used the lymph fluid to travel to the tonsils. Assessment question 7. How did the Streptococcus bacteria make its way from the tonsils to the lymph nodes? The bacteria made its way into the bloodstream and then on to the lymph fluid. The bacteria was already in the lymph nodes before it arrived at the tonsils. Interstitial fluid in the tonsils drained into the lymphatic capillaries.
