Fantastic Voyage a&P 2

Hello and welcome to this fantastic voyage we will be going on today. Can anyone recall the television show called the “Magic School Bus”? Well let me tell you a little bit about the “Magic School Bus”. The television show was about a bus being miniaturized so that the children in Ms. Frizzle’s class could take a field trip inside the human body and explore. The “Magic School Bus” is very similar to what we are going to do today. First, we will miniaturize the sub to only eight microns long. Then we will be injected into the femoral vein of a healthy twenty five year old female named Jennifer. Please buckle your seat belts, sit back and enjoy the ride as we get to explore the amazing structures inside the human body. Oh no, wait we have just been alerted that bacterium is invading the lower lobe of the right lung. Get ready to see firsthand how our body deals with infections. In the words of Ms. Frizzle “Take chances! Make mistakes! Get messy!” Before we can start out our journey I would like you to meet Mrs. Hart, she will be guiding us through Jennifer’s body.

We are now in the femoral vein which is located in the groin area by the upper thigh or the pelvic region of the human body (Saladin, 2007). As we travel towards the right lung, we arrive at the inferior vena cava which is one of the two main veins that provides deoxygenated blood to the right atrium of the heart (Adam, 2011). As we enter the end of the vein suddenly we rushed into the right atrium of the heart by the rapid flow of blood. The right atrium is the upper portion of the right chamber of the heart; this is the area where deoxygenated blood returns from the body to the right ventricle (Right Atrium, 2010). The right atrium is located anterior to the left-side counterpart and now that we have entered into the right atrium, which is the inferior vena cava. The inferior vena cava is at the bottom of the heart. Mrs. Hart said “look up and see all the amazing structures of the right atrium all...
