Fantastic tripGood evening! I come to you from inside a tiny submarine only 8 microns long! Now you're probably wondering why I'm inside a tiny submarine that's been shrunk so small, let me explain. My caregivers and I were alerted that this healthy 27-year-old woman has some form of bacteria that has invaded the lower lobe of her right lung. I will pilot my submarine into its lung so I can see better. My assistant will inject me into your femoral vein, which is in your leg, and I'll go north, through your heart, to your lungs. My sub has also been coated with a special substance so that the white blood cells don't think I'm a foreign object. I'm ready and the patient is ready, LET'S DO THIS! Now I communicate to you from the patient's femoral vein. I'm headed north towards his right lung. The femoral vein is one of the largest veins in the body. So far the trip has been smooth. I saw many different types of cells pass through the window of my submarine. I just saw an army of white blood cells heading in the same direction as me. They are most likely directed towards the bacterial infestation in the right lung. I also hear the heartbeat; makes a LUB-DUB sound. I can also feel the blood flow; it's making some kind of hissing noise. That noise reminds me of the ocean! The right femoral vein is now transforming into the external iliac vein; Now they are from the urinary system and the reproductive system. This is also known in the pelvic region. As we continue north, the eternal iliac vein is now called the common iliac vein. Continuing, the common iliac vein is now called the inferior vena cava. We are getting closer to the heart! We are in the abdomen of the body. There are several… half of the paper… the membrane helps keep dust particles away from our body. An extensive network of blood vessels is also present and normally appears pink (Shier, Butler, Lewis, 2010). So now we wait for the patient to sneeze. Chances are, once we sneeze, we'll come out covered in mucus! BIG!!!AH-CHO!!! In the end the patient sneezed through her nose! It was a very pleasant trip. It was so fascinating to go inside the human body and look closely at the cardiovascular and respiratory systems. It's just amazing how all of this happens inside our bodies and we don't even realize it's happening. It's also fascinating how the body automatically knows what to do when there is an infection of some kind. Now if you'll excuse me, I'm going to take a shower. Something about coming out of a human's nose that makes me feel disgusted.
