Unit 4 Assignment
Fantasy Voyage and Battle of the Lung
Hello everyone and welcome aboard! I am S Y. with Voyage Health. Today, we will embark together in my mini-sub and we shall travel through the body of this young lady named Lola. In this journey we will enter her body through the femoral vein and travel all the way to her lung.
Alert! Alert!
An alert just came and we are in for a surprise. Bacteria have invaded Lola’s lower lobe of her right lung and we shall report the invasion and document all we see.
Let’s proceed. We are being injected into the femoral vein close to the groin area. The femoral vein runs parallel with the femoral artery through the upper thigh and pelvic region of the body. (Yahoo Health, 2013)

Next stop. Right atrium. One of the four chambers of the heart, the right atrium lets deoxygenated blood to pass through the tricuspid valve into the right ventricle and from there to the lung to oxygenate. The tricuspid valve, also known as right atrioventricular valve is located between the two chambers and it looks like flaps that blocks blood flowing back into the atrium. (Yahoo Health, 2013) The right ventricle of the heart has the mission to pump the blood into the pulmonary artery via the pulmonary valve and pulmonary trunk right into the lungs. Ready to go through the pulmonary valve into the pulmonary artery? Here we go! Weeeee…..
We are steps away from the most magnificent oxygen factory you have ever seen. Short and wide, the pulmonary artery begins at the base of the right ventricle and with a considerable size of 1.2 inches in diameter and 2.0 inches in length. Interesting fact: the pulmonary artery is one of the only arteries that carry deoxygenated blood. The other artery is the umbilical artery in the fetus. This is just something I remembered from an Anatomy class I used to take in college. The main pulmonary artery extends from the right ventricle of the heart and branches into left and right pulmonary arteries. The left and right pulmonary arteries extend to the left lung and right lungs.(Bailey, Regina 2013)
Now just relax and sit back. Enjoy the ride to the lung! Going through the
Finally, as promised,
Once the blood cell gets to the superior vena cava it goes through the right atrium and the right ventricle, then through the pulmonary artery and into the lungs.
The right ventricle fills up tricuspid valve closes right ventricle contracts pulmonary valve opens the blood flows into the pulmonary artery pulmonary valve closes pulmonary artery splits into two vessels each going to the lungs.
It begins at the base of the heart’s right ventricle and is approximately 3 cm in diameter and 5 cm in length (Yahoo Health, 2012). It then splits into the left and right pulmonary arteries. The right pulmonary artery delivers oxygen depleted blood to the right lung. From the right pulmonary artery I have made it to the right lung. Once in the lung I will travel South West to reach the lower lobe of the right lung.
First the de-originated blood goes into the right atrium. And the originated blood goes through the left atrium. The right atrium then pumps blood through the tricuspid valve into the right ventricle, and the left atrium pumps blood through the bicuspid valve into the left ventricle. The right ventricle contracts, semi lunar valve opens and deoxygenated blood travels back to the lungs. The left ventricle contracts, semi lunar valve opens and oxygenated blood goes out to the body.
Likewise, Blood flows from the right atrium to the right ventricle, and then is pumped to the lungs to receive oxygen. From the lungs, the blood flows to the left atrium, then to the left ventricle, forming the complete circulation.
Usually, accessing vascular structures is done through a needle to puncture the vessel percutaneously, followed by a wire introduced through the needle to secure the vascular access. The needle is then removed and a sheath is advanced over the wire. Vascular sheaths are hollow structures with a built in diaphragm to prevent bleeding. Catheters are then placed into and out of the sheath with a minimal loss of blood.11
In a normal human being the heart correctly functions by the blood first entering through the right atrium from the superior and inferior vena cava. This blood flow continues through the right atrioventricular valve into the right ventricle. The right ventricle contracts forcing the pulmonary valve to open leading blood flow through the pulmonary valve and into the pulmonary trunk. Blood is then distributed from the right and left pulmonary arteries to the lungs, where carbon dioxide is unloaded and oxygen is loaded into the blood. The blood is returned from the lungs to the left
The left side of the heart, has the left atrium and ventricle that takes in oxygenated blood from the lungs and pumps it out of the aorta.
Pulmonary circulation transports deoxygenated blood from the right side of the heart to the lungs where the blood picks up oxygen and returns
The left chamber, lower at the heart, takes in oxygenated blood through the mitral valve from the left atrium while it contracts. The aortic valve leading to the aorta is closed while this occurs. At the same time, the aortic valve leading to the aorta is closed giving the ventricle the opportunity to fill with blood. The ventricles contract as both ventricles are full. When the left ventricles contract, the aortic valve opens as the mitral valve closes. When the mitral valve closes it prevents blood from coming back into the left atrium and the opening of the aortic valve giving way for the blood to flow into the aorta. From there it goes throughout the body. The left and right ventricles also contract together, but when the left ventricle
the tricuspid valve into the right ventricle. The blood then leaves through the pulmonary valve into
The right atrium is where the process begins. Then, blood travels through the tricuspid valve to the right ventricle, and from there to the pulmonary artery. Once the blood travels through the pulmonary artery, it reaches the lungs. While in the lungs, the blood goes through a gas exchange: deoxygenated blood gets oxygenated (The gas exchange takes place in the alveoli, which are tiny air sacs in the bottom of the lungs
Both the right and left atrium contract causing blood to flow though the two valves, and then into the left ventricle. The left ventricle pumps blood into the systemic circulation through the aorta. This systemic circulation system is much bigger than the pulmonary circulation system, which is why the left ventricle is so big. The blood on the left side of the heart is oxygenated. It becomes oxygenated when the deoxygenated blood passes through the right atrium and then flows into the left ventricle. It is then pumped along the pulmonary artery into the lungs where it is oxygenated. It then travels through the pulmonary veins back into the heart. It enters through the left atrium and then travels to the left ventricle. This process is repeated over and over again, to make blood continuously flow through the heart, lungs and body. This process ensures that there is always enough oxygen for the body to work
lungs. As I lined up for a third mile, I began planning. Through oxygen debt and ever-increasing
When blood goes into the heart in the right atrium, it has a lot of carbon dioxide in it. The heart transfers the blood into the right ventricle, and then into the lung. This is where the blood is able to receive oxygen, and it also explains why human lungs are an essential organ. The oxygenated blood is then transferred into the left atrium, and finally to the left ventricle. Once the blood is released from the left ventricle, it is circulated throughout the
