Arteries

The descending thoracic aorta passes down the thorax on the left side of the vertebrae.
It enters in the diaphragm in the abdominal cavity called the aortic hiatus and then becomes the abdominal aorta.
It then divides into the right and left common iliac arteries at the lower border of the 4th lumbar vertebra. Then divides again at the 5th and last lumbar intevertebral disc into the internal and external iliac artery.

By no means am I an expert in this area, however, I would like to contribute an opinion to this question. For many people, when drinking carbonated beverages, it is quite common to experience a tingling sensation to the neck and chest (commonly painful and uncomfortable) because of the gas that's built up. Unfortunately, many have difficulty burbing or passing the gases through. If you are one of those who must have their Pepsi-Cola or any type of carbonated drink, abstain from them for a few weeks and try to observe the difference. PS. I am not a professional; I speak from experience! A heart problem can cause your neck and chest to hurt.

The pulmonary artery is the main artery that carries blood to your lungs.

aorta has to withstand high blood pressure because of which it needs thick walls !!

The blood pressure and flow rate in veins is low. When the blood in them is moving upwards (e.g. in the legs) it can stagnate and may have a tendency to flow backwards in the vein. The valves prevent this back flow by closing.

The blood pressure and flow rate in arteries is high. Blood flow in the arteries cannot stagnate.

subclavian artery , carotid artery , vertebrobasilar artery, vertebral artery and cerebral artery. in these, the vertebral arteries are divided into 3 namely anterior, posterior and middle cerebral arteries and these supplies to brain.

carotid arch, systemic arch ,pulmocutaneous arch, cutaneous artery ,coeliaco mesentric artery, renal artery ,posterior mesentric artery, illiac artery.

The aorta receives blood directly from the left ventricle of the heart.

The coronary arteries. These leave the aorta and branch out over the heart. Blood only flows though these vessels during diastole because during systole they are blocked off by the aortic valve.

The two main vessels that arise from the Sinus of Valsalva, located just above the aortic valves, are the right and left cornary arteries. The right coronary artery mainly supply the right ventricle and the sinoatrial node. The left main artery is divided into the left anterior descending artery and the left circumflex artery. The left anterior descending artery mainly supplies the anterior and septal portion of the heart, namely the left ventricle. The left circumflex artery supplies the lateral walls of the left ventricle. Finally, the posterior descending artery can arise from either the right or left coronary artery. If the posterior descending artery arises from the right coronary artery, the heart is termed right heart dominant, which is seen in approximately 70% of individuals. If the posterior descending artery arises from the left circumflex artery, it is termed left heart dominance. It is also possible for the posterior descending artery to arise from both the right and left coronary artery. In this configuration, the heart is considered co-dominant. The posterior descending artery mainly supplies the inferior wall of the left ventricle and the inferior portion of the septal wall.

Arteries actually have 5 layers, it is the veins that have 3.

Arteries have:

-the Outer coat

-Elastic layer

-Middle coat (thin)

-Another elastic layer

-Endothelium

The pulmonary artery, which takes deoxygenated blood from the right side of the heart to the lung to be reoxygenated. The pulmonary vein then carries oxygenated blood back to the left side of the heart to be pumped back to the rest of the body.

The pulmonary artery goes away from the heart, so does not actually do anything for the heart. However, once blood enters the heart via the venae cavae (the veins that bring the body's entire blood supply into the heart) it then travels through the right atrium to the right ventricle, through yes!, the pulmonary artery (pulmonary means pertaining to the lungs) . From there the blood travels to the lungs through the pulmonary artery and branches into capillaries, where the exchange of carbon dioxide to oxygen occurs. The blood then travels back to the heart through the pulmonary vein, the exception to the rule that veins are oxygen-poor. From there the blood enters the left atrium, is pumped into the left ventricle, and from there is pushed into the aorta where it travels to supply the entire body with the now-oxygenated blood.

So, that is the relationship the pulmonary artery has with the heart. The cornonary arteries, which feed off of the aorta, are what supply the heart itself with blood. Just in case that's what you were looking for by asking this question.

Hope that answers your question!!!!!

Arteries carry blood away from the heart, e.g aorta and pulmonary artery, arteries are thick, the inside of them is made of epithelial cells as they are smooth, they help blood flow more easily, the middle layer is muscle, these can go along with pulses to help them. the outside is made of elastic tissue, this enables it to withstand high pressures. veins have valves in them to stop backflow of blood, they all carry deoxygenated blood apart from the pulmonary vein, they have less elastic tissue in them than arteries.
Pulmonary Arteries lead from the heart to the lungs. Systemic arteries go everywhere else. Consequently, the pulmonary arteries are usually slightly smaller and thinner. There is also less of them.
Arteries carry blood away from the heart. Veins carry blood toward the heart.
Veins have a "check valve" that prevents the blood from going the wrong direction in our body. 1. Wall of vein is much thinner in diameter as compared to those of artery. 2. The vein has a thin fibrous layer whereas artery has much thicker inextensible fibrous layer.

Aorta is thicker because it has greater pressure of outflow to deal with from the left ventricle. Blood leaving the heart into the aorta has great pressure because the blood has to be carried all over the body, whereas the pulmonary trunk only pumps blood to the lungs which is an area of lower pressure.

The aorta is sometimes concidered to be an organ because it is so large that it is made up of several different tissues (a simple definition of an organ being that it is made up of more than 1 tissue) although it is still only a very large artery and so is not usually described as an organ but a large blood vessel.

The aorta has significantly thicker walls than the superior and inferior venae cavae as the aorta is an artery that must respond to significant intraluminal pressures whereas the venae cavae are veins that have minimal intraluminal pressure.

What is the main pulmonary artery? * Arteries are vessels that carry blood away from the heart. The main pulmonary artery extends from the right ventricle and branches into left and right pulmonary arteries. The left and right pulmonary arteries extend to the left lung and right lung. Function: * Carries de-oxygenated blood from the right ventricle to the lungs. http://biology.about.com/library/organs/heart/blpulmartery.htm :D im doin biology toooo!!!

Arteriorrhaphy is the medical term for suture of an artery. This is when a surgeon will close up an artery. If an artery was severed, they would reattach both sides of the blood vessel walls, like stitching up a deep cut. A related term, angiorrhaphy, means suture of any vessel.

The atria

Actually, it is the contractions (squeezing) of the ventricles (the lower parts of the heart), not the atria (the upper parts), that do the pumping. That's why the lower part of the heart is larger, and the muscular walls are thicker.

The atria receive the blood from the body and pump it down into the ventricles.

Arteries are not one cell thick. They are multicelluar in their formation. They contain three distinct layers; tunica interna (or intima made of endothelial tissue), tunica media (muscular tissue), and tunica externa (serous membrane).
