Fantastic Voyage – Battle of the Lung
Unit 4 Assignment
May 22, 2014
Good morning everyone! This is Brittany Carpenter reporting to you live from inside the body of Laura, a healthy 30 year old female. Today I will be touring the inside of Laura’s body inside a min-sub that has been shrunk to only 8 microns long. While I wait for the green light to go, let me explain where I currently am. Right now I am located in the right femoral vein, which is located in the upper thigh and pelvic region of the body. It is also one of the largest veins in the venous system. The femoral vein’s purpose is to take all the blood in the lower region of the body and deliver it to the heart via the iliac vein. Today’s tour will begin, here, in the right femoral vein and take us through the body. I will be explaining everything we see as we go. Maybe we will be able to witness something exciting.
I just received the green light, so here we go! Right now we are traveling up the right femoral vein. Our first siting is a red blood cell, or erythrocyte. These cells are responsible for transporting oxygen from the lungs to the rest of the body. Their shape is very strange, but serves a purpose. You can see how it looks almost like an inner tube, round and concave in the center. Red blood cells have capability to change shape, without breaking, to fit through tiny capillaries. I can also see white blood cells, which are responsible for fighting infections and is part of our immune system.
I just received word that a bacterium is invading Laura’s lower lobe of her right lung! Now you will all be able to see first-hand how the body fights off infection! You will not want to miss this! So from here we are going to travel to the right lung and see what this bacterium looks like.
In order to get to the lungs, we need to travel to the heart. As we continue to make our way to the heart, we merge with the right external iliac vein....
