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
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
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
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
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
Tennessee Williams and Cat on a Hot Tin Roof Tennessee Williams has been described as the most literary of the major dramatists and one of America's best playwrights (Bloom, p.2). He has been praised by critics for his compassionate understanding of the spiritually downtrodden (Gale Databases, p. 8). One of his most famous plays, Cat on a Hot Tin Roof, has been described as his most powerful, and deals with the then taboo subject of homosexuality (Becker, p. 2). Tennessee Williams, whose
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
without pulmonary sequestration is the rarest form of anomalous systemic arterial supply to the lung . This condition is characterised by an aberrant systemic arterial branch, most commonly arising from the thoracic portion of the descending aorta or the abdominal aorta, supplying an area of lung parenchyma with normal bronchopulmonary system. The left lower lobe is most often involved, and there is commonly an atr... ... middle of paper ... ... Various treatment modalities have been described
window and clockwise rotation, the pulmonary artery (PA) bifurcation can be seen. In this view, the LPA goes leftward of the descending thoracic aorta toward the left scapula. From this view of the branch pulmonary arteries, counterclockwise rotation of the transducer toward 12 o’clock demonstrates the long-axis of the PDA, which is located between the LPA and the descending aorta. In patients with associated coarctation the posterior shelf can also be visualized. Suprasternal views: Suprasternal long
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
ascending aorta sends fully oxygenated blood to the coronary arteries, the head, and the upper extremities. Only a small portion of the LV cardiac output streams through the aortic arch and supplies flow to the thoracic aorta.
Since the heart is divided into two sections this means that each section has a specific job. The right side of the heart ... ... middle of paper ... ...ch it is then distributed to the rest of the body. The descending aorta goes behind the heart and down the center of the body. From the aorta, blood is sent off to many other arteries and arterioles (very small arteries) where it gives oxygen and nutrition to every cell in the body. At the end of the arterioles are, guess what, capillaries. The blood
The Left Descending Artery (LDA) or more affectionately named the “Widow Maker Artery” due to its low survivability rate if blocked, is the vessel in which the deadliest of heart attacks takes place. Due to its location, right in front of the heart, and function, supplying the heart with blood, makes it the hardest to operate on. The Left Descending Artery descends directly from the main portion of the Aorta and, if blocked for too long (due to plaque or surgery)
runs through the bicuspid valve. From the bicuspid valve, the blood enters the left ventricle and is pumped through a fourth valve, the aortic semilunar valve, and courses through the aortic arch. From the aortic arch, the blood rushes down the descending aorta and runs through the celiac trunk. Said trunk branches off into 3 arteries, one being the common hepatic artery. From the common hepatic artery, blood branches off to the right hepatic and cystic arteries. It is the latter that ultimately supplies

The distal end of the LIMA is anastamosed to the left anterior descending artery (LAD) whereas the proximal end remains attached to the left subclavian artery. Most CABG procedures use LIMA to bypass the LAD because it has a greater long-term patency than an SVG. The use of LIMA is also associated with a greater rate
tube called the ureter. It leads down to the urinary bladder where the urine is stored for a while and after storage it will squeeze and release out urine to the urethra. The flow of blood into the kidneys start with renal arteries from the abdominal aorta, branches of the renal artery is the segmental arteries, it forms interlobar arteries that go up the renal columns, between the pyramids. It leads to an arch shape called arcuate arteries that go over the pyramids, interlobular arteries go into the
heart is encircled by blood vessels. These blood vessels are called coronary arteries. They originate in the aorta and supply the heart muscle with oxygen rich blood. Coronary arteries consist of Right Coronary Artery, that branches into Marginal RCA and Posterior Descending Artery, and Left Main Coronary Artery, which branches into Left Circumflex, Marginal LCA and Left Anterior Descending Artery. In order for the heart to function properly the coronary arteries should be constantly supplying oxygen

Structure, Function & Enzymes The Circulatory System The human circulatory system, or cardiovascular system, is made up of the heart, blood and blood vessels. The circulatory system has three functions: transportation of substances, protection from disease and regulation of temperature. The heart pumps blood to our body tissues via a network of blood vessels. Humans have a closed circulatory system that is in two parts; the systemic circulation and the pulmonary circulation. The systemic system
