Definition An AAA (abdominal aortic aneurysm) is defined as enlargement of at least 3 cm of the abdominal aorta. The majority of abdominal aortic aneurysms begins below the renal arteries and ends above the iliac arteries. The exact cause of (AAAs) is unknown. However, it is thought to be due to a degenerative process of the abdominal aorta caused by atherosclerosis. Artherosclerosis represents a response to vessel wall injury caused by inflammation, genetically regulated defects in collagen
more detail, than just two little words. The aorta is the largest artery in the body, responsible for the transfer of oxygenated blood from the heart to every organ of the body. Understandably, any disruption in the integrity of the aorta could have catastrophic consequences. An aortic dissection occurs when a tear in the inner layer of the aorta develops. As the tear expands, blood will eventually begin to spill out of the tear and continue down the aorta in between the inner layer and outer layer
safety and practicality of endovascular stent graft repair. Endovascular stent graft repair is designed to help reinforce a weakened aorta. Endovascular surgery is performed inside the aorta using thin, long tubes called catheters to place a stent surrounded with a fabric liner. Endovascular stent grafting uses an endovascular stent graft to reinforce the wall of the aorta and to help keep the damaged area from rupturing and developing into a potentially serious health problem that can be fatal and cause
What is Marfan Syndrome? For this genetic disorder assignment, I chose Marfan Syndrome, which is a mutation in your connective tissue. Connective tissue holds our body together by holding the blood where it is suppose to be, the organs in place and keep our tissue in place. This connective tissue also helps you grow in height and go through the stages you need to. The disorder results in abnormally long and thin digits in your genes and also frequently in optical and cardiovascular defects. Our
It took me eighteen years to appreciate the profound impact my grandmother had on my life. She was the type of that always had her words of wisdom to pass on to her grandchildren, and the kind heart who donated her time to those who needed it. Being able to grow and learn with such a strong role model I became more like her each day. I started to use her words of wisdom in my daily life, and I remembered the importance of making time for those in need, both friends and strangers. My grandmothers
branching off of the heart is largest artery in our body and is known as the aorta. The aorta supplies oxygenated blood to our body. The aorta runs along the midline of our body and has many other vessels that stem from it to deliver the blood to a specific location. The aorta has several different names, depending on the location in the body. As it comes off of the heart at the left ventricle it is called the ascending aorta. It is located in the anterior mediastinum and is approximately three to
Implications of the Dinosaur Heart Discovery The article from Science News, “Telltale Dino Heart Hints at Warm Blood”, by Tina Hesman and the Journal article it was based on from Science, ”Cardiovascular Evidence for an Intermediate or Higher Metabolic Rate in an Ornithischian Dinosaur”, by Paul Fisher and others both offer a new perspective on the topic to be discussed, however there are some key differences between the two articles. How the two articles differ will be discussed later on in
Marfan syndrome is an inherited disorder that affects the connective tissue of the body (“What is Marfan Syndrome?” n.d.). The connective tissue plays a vital role in supported the tendons, heart valves, cartilage, blood vessels, and more parts of the body (“Connective Tissue,” n.d.). “What is Marfan Syndrome?” (n.d.) explains that the condition has no cure, and those who have it lack strength in their connective tissue, affecting their bone, eyes, skin, nervous system, and lungs. Furthermore, Marfan
atrium and right ventricle make up the right side of the heart. Each side is important but the left ventricle and left atrium is the most important, and I will tell you why. The left ventricle receives blood from the left atrium and pumps into the aorta. The aorta pumps oxygenated blood to the rest of the body. If someone shot you in your left ventricle, you would most certainly die. That is why it is the most important. It pumps blood to the rest of your body. The right ventricle is important too. The
Warm Blooded Versus Cold Blooded Dinosaurs At a time, scientists believed all dinosaurs were cold-blooded. However, with a recent discovery of a dinosaur found with a fossilized heart in the northern part of South Dakota in 1993, many paleontologists are starting to think that there were some dinosaurs that were warm blooded. Dinosaurs were first believed to be cold-blooded because they were thought to be related closely to reptiles which are cold-blooded creatures. Cold-blooded animals
vein and common carotid artery, were observed. This process was repeated bilaterally and both right and left appeared normal. When tracing the course of the right common carotid artery, the brachiocephalic trunk was noticeably absent. Instead, the aorta in this particular cadaver had 4 branches
Summary Patients that come in in cardiogenic shock during there echocardiogram need to be evaluated in a whole looking for any abnormalities. Diastole dysfunction, systolic dysfunction, any possible shunting issues, aortic stenosis, coarctation of the aorta or
has a thick muscular and elastic wall and a large diameter. The main function of an artery is to carry blood that is rich in oxygen away from the heart to all parts of the body. The aorta is the main artery of the heart. All blood that leaves the heart is fed through the aorta to the rest of the body. As the aorta starts to get farther away from the heart, the diameter of the blood vessel starts to decrease and it begins to branch off. It branches into arterioles which are just smaller arteries
Tetralogy of Fallot is a congenital heart disease which involves four different heart defects in one. The four different heart defects are a large ventricular septal defect (VSD), Pulmonary Stenosis, Right ventricular hypertrophy, and an overriding aorta. These congenital defects change the normal flow of blood thro... ... middle of paper ... .... Tetralogy of Fallot occurs during fetal growth when the baby’s heart is developing. In most cases the cause of this disease is unknown. Prevention
and blood flows into the ventricles. The ventricles contract (systole) and the atria relax (diastole) and the pressure closes the valves allowing the deoxygenated blood to enter the heart to become oxygenated and a higher pressure when reaching the aorta oxygenated to enable it to circulate throughout the body. Without blood pressure, blood would not move. Blood itself, transports oxygen, nutrients, hormones and enzymes around the body. It transports carbon dioxide and waste materials from the
Introduction: The transport system in our body that carries blood is known as the circulatory system. This system allows the blood to carry essential nutrients such as amino acids, oxygen, and hormones to the cells in all parts of our body to ensure they are able to maintain body temperature and pH known as homeostasis. The oxygen-rich blood enables cellular respiration to occur efficiently which is vital for humans to continue to survive. It also carries cellular waste such as carbon dioxide which
blood through our bodies. Our heart has a superior and inferior vena cava, right and left atrium, a tricuspid valve, right and left ventricle, a pulmonary valve, right and left pulmonary artery, left and right pulmonary vein, a bicuspid valve, and an aorta. Who ever knew our heart was so.. HELP The heart sits
pregnancy which leaves the left side of the heart underdeveloped and small. Normally, the right side flows blood to the lungs where oxygen is enriched before it travels to the heart’s left side while the left side of the heart pumps blood into the aorta which flows oxygen-rich blood to the body. In HLHS, the left side of the heart is not able to pump oxygen-rich blood to the body efficiently because the left ventricle is underdeveloped or small. In this case, the right side of the heart pumps the
does not have nicotine however professor Charalambos Vlacholoulous of University of Athens Medical School conducted a study with a group from the University to test the difference vaping has on the aorta compared to smoking. Both smoking and vaping stiffens the heart and this is bad because “if the aorta is stiff, you multiply your risk dying either from heart disease or from other causes.” Fox News (2016). This study shows how vaping proves to be harmful to the health of a vapers heart. A major
As an individual thinks about the heart they may not fully understand the amount of work that the heart does in order to keep the blood flowing throughout the body. The heart is made up of four chambers and two pumps. The top half of the heart is made up of a right and left atrium while the bottom portion of the heart is made up of a right and left ventricle. The right side of the heart pumps blood throughout the pulmonary circuit which supplies blood to the lungs. While the left side of the heart
