Battle of the Lung
Hello there, my name is Cassie and I will be your tour guide as we take our journey through the wonderful body of Lillian Jones. We have been scheduled to tour the lower lobe of her right lung. She has been feeling very ill and her doctor has informed her there is a bacterium invading her lung! We will be starting off in the right femoral vein and traveling up the body through the right pulmonary artery into the lower lobe of her right lung.
Alright folks lets get started with our tour by getting a better understanding of our starting point! We are located in the femoral vein in the right leg. The femoral vein is right next to the femoral artery, which is by the femur. The femur is a large bone located in your thigh. This vein has a large blood supply which pumps at a fast speed. If any damage were to occur to this vein there would be major blood loss that could result in death. The vein separates into different branches and gets blood from veins that are located in the back of the thigh. The vein connects with the medial femoral vein and lateral circumflex vein. The femoral vein then stops at the inguinal ligament because it becomes part of the external iliac vein (Healthlines RSS News, 2005). Our destination is the lower lobe of the right lung and we will be traveling there through the pulmonary artery. Lets get started on our trip shall we? As you look about you we will pass many red circular concaved cells called red blood cells. These cells are the most abundant in the body at an average of 4,600,000 per cubic millimeter within a woman. Each one lasts about 120 days inside the bloodstream and is then removed from the blood by macrophages. The primary function of these little cells is to bring oxygen to the cells of the body from the lungs (Bianco, Carl 1998). Now you might be wondering how all this blood is flowing together? Veins have a one way directional and their direction is toward the heart. The walls of veins are thin,
