Choose one concept in our lesson today, give a brief explanation about the concept and cite how would you apply this learning in your everyday life.
As someone who is currently experiencing a runny nose, I learned that this occurs because my immune system functions to fight off the invading infection/virus, which in this case, the common cold. I can also feel the swelling of my lymph nodes and a minimal increase in temperature. Lymph nodes swell since more blood cells naturally pile in to fight off any germs or infection that may pass through the lymph fluid. I always get irritated when I have symptoms such as runny nose, cough, sore throat, fever, but now I was able to appreciate that this is how my body's immune system naturally does its job to fight against any bacteria or infection. I experience nasal discharge because my body produces extra mucus to trap the virus before it can even reach my lungs. It's nothing to worry about because my body will recover on its own. I can apply my learning by making sure I drink plenty of water to avoid dehydration and get enough sleep now that I learned how important sleep is for the functioning of my immune system.
