Good morning everyone! Signing on, India Hornsby with ASAP Health. I will be reporting live inside Mrs. Frizzle. She has been under the weather for about two days now. A bacterium is invading the lower lobe of her right lung. It’s my job to pilot the invasion and do a live report on what I see. I will enter from the right femoral vein and follow a path to the lower lobe of the right lung via the right pulmonary artery. I will be describing the structures that I pass by and through. Once I have reached the lung, I will describe the structures that I see and discuss how the body fights against the invader. After that I will exit the body cross the alveolar membrane on a path and out the nose. I will enter Mrs. Frizzle body through the femoral vein. The femoral vein is located in the upper thigh and pelvic region of the body and runs close to the femoral artery (Yahoo Health, 2012). It’s one of the larger veins in the venal system (Yahoo Health, 2012). The femoral vein returns blood in the leg to the heart via the iliac vein (WiseGeek, 2012). Continuing North from the femoral vein I will pass through the inguinal ligament. The inguinal ligament forms a band that runs from the anterior superior iliac spine to the pubis area of the spine (Yahoo Health, 2012). It serves as a base to the inguinal canal because hernias can form there. The main function of the inguinal ligament is to protect the tissue that is constantly moving in the trunk and lower extremities of the body (Yahoo Health, 2012). From the inguinal ligament still heading north I will pass through the external iliac vein. The external iliac vein is a continuation of the femoral vein above the inguinal ligament. It starts at the groin and runs along the edge of the pelvic area (Yahoo Health, 2012). When it is combined with the internal iliac vein it forms the common iliac vein. The external iliac vein drains the leg and lower part of the anterior abdominal wall (Merriam-Webster, 2012). As I continue on I will pass the internal iliac vein to the East. The internal iliac vein combines with the external iliac vein to form the common iliac vein. It drains the pelvis, gluteal, and perineal regions (Merriam-Webster, 2012). Next I will be passing through the common iliac vein, which is formed by the external and internal iliac veins. It allows blood circulation from the lower abdomen and legs (Wise Geek, 2012). The hepatic vein carries deoxygenated blood out of the liver and into the inferior vena cava (Wise Geek, 2012). The blood that was used to feed the liver and the blood from the gastrointestinal tract, spleen, pancreas, and gallbladder is transported through the hepatic vein. From the hepatic vein I will then pass through the inferior vena cava. The inferior vena cava runs behind the abdominal cavity and alongside the right vertebra column of the spine (Yahoo Health, 2012). It carries oxygen depleted blood from the lower part of the body back to the heart. The inferior vena cava empties into the right atrium (Yahoo Health, 2012). Next stop is the right atrium. It’s located on the lower back side of the heart. The right atrium is one of the four chambers of the heart. Blood enters the heart through the two atriums (Yahoo Health, 2012). Oxygen depleted blood enters the right atrium via the inferior and superior vena cava (Yahoo Health, 2012). I will then pass through the tricuspid valve. It forms the boundary between the right ventricle and atrium (Yahoo Health, 2012). The tricuspid valve has tree flaps that keep blood from going back into the right atrium when they are closed. Next I will be moving on to the right ventricle. It is one of the four chambers of the heart, located at the lower left portion of the heart below the right atrium and opposite the left ventricle (Yahoo Health,...
