INVESTIGATION

       As we all know microorganisms are everywhere. They can be in the air, water, soil and in any particles. All microbes are not pathogenic for humans, but some are pathogenic and even deadly. Recently my brother in law got sick and he went to the hospital for a checkup, after his Dr. examine him and with all the lab result, he is diagnosed with acute bronchitis. His diagnosis lead me to investigate what causes his disease?

Bronchitis is an inflammation of the bronchial tubes. Usually acute bronchitis caused by virus, but bacteria can also a cause of bronchitis. These virus or bacteria can cause inflammation or infection to the bronchial tubes.

Signs and symptoms of acute bronchitis include sore throat, fatigue (tiredness), fever, body aches, stuffy or runny nose, vomiting, and diarrhea. But the main symptom is that a persistent cough.

SPLEEN

     Today, when I attended my microbiology class, I learned a lot of things. One thing struck me in particular. My professor asked a question about the function of the spleen. I had no idea what it did. I knew that it is somewhere in our body, but that was the only information I knew about it. This led me to investigate the location and the detail function of the spleen.

It is an organ which is located in the upper far left part of the abdomen and its commonly fist shaped, purple and about 4 inches long. Most of us think the spleen has less role in our body, but the spleen has many important functions just like any other organ.

The function of the spleen includes: filtration of the blood as part of the immune system, recycling old red blood cells, storage site for platelets and white blood cells are stored there. Another function of the spleen is that, it helps fight certain kinds of bacteria that cause pneumonia and meningitis.
