A&P2 Fantastic Voyage, Unit 4
So today kids we will be going on a “fantastic voyage” thru the body of a healthy female. We will first need to find a guide that can get us from the right femoral vein to the lower lobe of the right lung and then to exit out of the nose. The reason for this is because we were just informed that the female’s body was invaded by a bacterium, which is invading the right lung and this is our only hope of getting out of her body. Before we can start our journey I would like you to meet Mr. Windzel, he will be guiding us through the females body today. We are also going to be miniaturized to 8 microns long so that we can be injected into the femoral vein. Now that we have been miniaturized we can start our journey, we are now in the femoral vein, which is located at the right of the thigh and as we move our way up the vein we will being going past the external iliac, which is formed with the common iliac. The common iliac veins are the vessels that bring the blood to the heart. It has 2 main veins, which are joined together to form the inferior vena cava. The function of this vein is to bring the de-oxygenated blood from the legs as well as the other lower regions of the body to the right atrium. Now that we are at the inferior vena cava let’s see what it has to offer for us. The vena cava are the 2 largest veins in our body” I know crazy huh?!” They carry d-oxygenated blood as well, but form different areas of the body and then to the right atrium of our heart. Moving right along, we now can see the right atria. The right atria is part of the heart, which is the upper chamber, which receives the de-oxygenated blood form our body from the vena cava and is then pumped into the right ventricle of the heart, which is the lower chamber of the heart. After it has done so it will move its way to the lungs under low pressure, which is via the pulmonary artery and there the blood will be turned into oxygenated blood. Between the right atria and the right ventricle
