what part of the body is the aorta

Full Answer

Where does the aorta go once it leaves the heart?

The aorta is the main arterythat carries blood away from your heartto the rest of your body. After the blood leaves the heartthrough the aortic valve, it travels through the aorta, making a cane-shaped curve that connects with other major arteriesto deliver oxygen-rich blood to the brain, muscles, and other cells. Can you feel your aorta?

Is the aorta on the left or right side?

The aorta, normally on the left side of the body, may be found on the right in dextrocardia, in which the heart is found on the right, or situs inversus, in which the location of all organs are flipped. Variations in the branching of individual arteries may also occur.

What does the aorta do in the body?

The aorta is the main artery that carries blood away from your heart to the rest of your body. The blood leaves the heart through the aortic valve. Then it travels through the aorta, making a cane-shaped curve that allows other major arteries to deliver oxygen-rich blood to the brain, muscles and other cells.

What causes the aorta to rupture?

Traumatic aortic transection, also known as aortic rupture, is the near-complete tear through all the layers of the aorta due to trauma such as that sustained in a motor vehicle collision or a fall. This condition is most often lethal and requires immediate medical attention.

Is the aorta in the neck?

The aorta is the largest artery in the body. It carries oxygen-filled blood from the heart to different organs in the body. The aorta starts at the heart's left ventricle, arches upwards towards the neck, then curves back downward, extending into the abdomen.

What does an enlarged aorta mean?

What is an Enlarged Aorta or Aortic Aneurysm? The aorta is your largest artery and it brings oxygenated blood to all parts of the body. If the walls of the aorta become weak, an enlargement can occur, which is known as an aortic aneurysm.

Can your aorta explode?

About abdominal aortic aneurysms Large aneurysms are rare, but can be very serious. If a large aneurysm bursts, it causes huge internal bleeding and is usually fatal. The bulging occurs when the wall of the aorta weakens.

What causes aorta to rupture?

Traumatic aortic transection, also known as aortic rupture, is the near-complete tear through all the layers of the aorta due to trauma such as that sustained in a motor vehicle collision or a fall. This condition is most often lethal and requires immediate medical attention.

What is the life expectancy of someone with an aortic aneurysm?

Patients with AAAs larger than 7.0 cm lived a median of 9 months. A ruptured aneurysm was certified as a cause of death in 36% of the patients with an AAA of 5.5 to 5.9 cm, in 50% of the patients with an AAA of 6 to 7.0 cm, and 55% of the patients with an AAA larger than 7.0 cm.

Can you survive an aortic aneurysm?

Yes, you can live with an aortic aneurysm, and there are many ways to prevent dissection (splitting of the blood vessel wall that causes blood to leak) or worse, a rupture (a burst aneurysm). Some aortic aneurysms are hereditary or congenital, such as bicuspid aortic valve, infection or inflammatory conditions.

Are there any warning signs of an aortic aneurysm?

5 warning signs and symptoms that aortic aneurysm might be suspected include: 1) Chest tenderness or chest pain, dizziness or light-headedness, back pain, coughing up blood (hemoptysis) and loss of consciousness due to the ruptures.

Which side of the body is the aorta located?

For people that have dextrocardia (a condition where the heart is located on the right side of the body), the aorta is usually on the right side instead of on the left side. 3  The same applies to people who have a condition called situs invertus, where all the organs are on the opposite side of where they usually are—like a mirror image.

How many parts are there in the aorta?

Four Parts of the Aorta. Ascending aorta. Aortic arch. Descending aorta. Abdominal aorta. The aorta is divided into four parts: 2 . Ascending aorta: This is the first part of the aorta and it is connected to the left ventricle of the heart (the part that pumps oxygenated blood to the body's tissues and organs).

What is the descending aorta?

Descending aorta: This is the part of the aorta that travels downward from the aortic arch through the chest. It is also known as descending thoracic aorta or simply thoracic aorta.

What is the birth defect of the aorta?

There is a birth defect known as coarctation of the aorta, in which a part of the aorta is significantly narrower than it ordinarily should be. The narrowing is usually found right after the arteries that supply blood to the head and arms have arisen from the aorta. 4  This narrowing occurs when the baby's aorta doesn't form properly while it's in the womb and its effect is that it doesn’t let blood flow to the body properly. This variation causes high blood pressure and eventual heart damage if it’s not corrected.

What is the clinical significance of an aortic aneurysm?

There are several conditions with serious complications that center around or affect the aorta. Aortic aneurysm: An aortic aneurysm is a weakened point on the aorta. It occurs when the aorta is not able to contract and expand to accommodate the passage of blood properly.

What is the largest artery in the body?

The aorta is the largest artery in the body to which all other major arteries are connected. 1  It is a big tube-like structure, usually about 1 inch wide in diameter, although its size varies proportionally to the height and weight of the person.

Where does the ascending aorta start?

The ascending aorta starts at the aortic valve which closes and opens to stop and allow the flow of blood from the heart into the aorta. Aortic arch: This is the part of the aorta that curves upward toward the head and neck. It starts where the ascending aorta ends.

Which part of the aorta travels down the body?

The aorta then arches downwards and to the left. This part is the aortic arch. From here, the aorta travels down the body. This last part is known by doctors as the descending aorta.

Where does the aorta start?

The aorta begins at the aortic valve, which separates the aorta from the left ventricle of the heart. The left ventricle is the last chamber that blood travels through as it moves through the heart.

Why is the aorta important?

The aorta is essential for health because it is the main artery supplying oxygenated blood to the body. Every tissue and organ in the body needs oxygenated blood to stay alive.

What causes a thoracic aortic aneurysm?

Thoracic aortic aneurysms occur in the chest, often as a result of high blood pressure or sudden injury. However, those with connective tissue disorders can also develop a thoracic aortic aneurysm. The symptoms include:

What is the largest vessel in the body?

The aorta is a large artery that transports oxygenated blood away from the heart and to the rest of the body. It is the largest vessel in the body, measuring more than 1 inch wide in some places.

What is the most serious condition that affects the aorta?

One of the most serious conditions that affects the aorta is an aortic aneurysm.

How to treat an aortic aneurysm?

Doctors may treat aortic aneurysms with medications, surgery, or both. Medications can help lower an individual’s blood pressure, reducing the risk of developing an aortic aneurysm.

What are the three parts of the aorta?

Most common one, and the one we will use in this article, is the classification of the aorta into three parts; the ascending aorta, aortic arch and the descending aorta. The descending aorta is the longest part, further subdivided into thoracic and abdominal aorta, with the diaphragm being the anatomical division between the two.

Where does the aorta originate?

Being the first segment of the systemic circulation, the aorta originates directly from the heart. It begins from the aortic orifice found at the base of the left ventricle. It is separated from the ventricle by the aortic valve, that consists of three semilunar cusps; the right, left and posterior cusp.

What is the largest artery in the body?

It is the largest artery in the body, with its largest diameter being approximately 4 cm at the aortic root decreasing with distance; being about 3.5 cm in the ascending aorta, and about 2.5 cm in the abdominal aorta. The main function of the aorta is to transmit oxygenated blood from the heart to the rest of the body.

Why does the thoracic aorta have different relations with the esophagus?

To clear out any confusion, the reason why the thoracic aorta has several different relations with the esophagus is due to the course of the esophagus through the mediastinum. The esophagus is initially laterally to the right of the thoracic aorta, then as it descends it crosses the thoracic aorta anteriorly.

Which artery is the first and largest branch of the aortic arch?

Brachiocephalic trunk: also called the brachiocephalic artery, is the first and largest artery that branches off the aortic arch.

Which artery runs upwards?

At the beginning of its course, the aorta runs upwards as the ascending aorta then shortly after arches laterally to the left, forming the arch of aorta.

How many pairs of arteries are there in the posterior intercostal artery?

Posterior intercostal arteries: consist of 9 pairs of arteries that run between the ribs and supply the intercostal spaces.

Where is the aorta located?

The aorta ( / eɪˈɔːrtə / ay-OR-tə) is the main and largest artery in the human body, originating from the left ventricle of the heart and extending down to the abdomen, where it splits into two smaller arteries (the common iliac arteries ).

Which side of the body is the aorta located?

The aorta, normally on the left side of the body, may be found on the right in dextrocardia, in which the heart is found on the right, or situs inversus, in which the location of all organs are flipped. Variations in the branching of individual arteries may also occur.

What are the aortic arches?

The aortic arches start as five pairs of symmetrical arteries connecting the heart with the dorsal aorta, and then undergo a significant remodelling to form the final asymmetrical structure of the great arteries, with the 3rd pair of arteries contributing to the common carotids, the right 4th forming the base and middle part of the right subclavian artery and the left 4th being the central part of the aortic arch. The smooth muscle of the great arteries and the population of cells that form the aorticopulmonary septum that separates the aorta and pulmonary artery is derived from cardiac neural crest. This contribution of the neural crest to the great artery smooth muscle is unusual as most smooth muscle is derived from mesoderm. In fact the smooth muscle within the abdominal aorta is derived from mesoderm, and the coronary arteries, which arise just above the semilunar valves, possess smooth muscle of mesodermal origin. A failure of the aorticopulmonary septum to divide the great vessels results in persistent truncus arteriosus .

What is the descending aorta?

The thoracic descending aorta gives rise to the intercostal and subcostal arteries, as well as to the superior and inferior left bronchial arteries and variable branches to the esophagus, mediastinum, and pericardium.

What is the aorta called after it passes through the diaphragm?

After the aorta passes through the diaphragm, it is known as the abdominal aorta. The aorta ends by dividing into two major blood vessels, the common iliac arteries and a smaller midline vessel, the median sacral artery.

How is the aorta classified?

In anatomical sources, the aorta is usually divided into sections. One way of classifying a part of the aorta is by anatomical compartment, where the thoracic aorta (or thoracic portion of the aorta) runs from the heart to the diaphragm. The aorta then continues downward as the abdominal aorta (or abdominal portion of the aorta) ...

Where does the abdominal aorta begin?

The abdominal aorta begins at the aortic hiatus of the diaphragm at the level of the twelfth thoracic vertebra. It gives rise to lumbar and musculophrenic arteries, renal and middle suprarenal arteries, and visceral arteries (the celiac trunk, the superior mesenteric artery and the inferior mesenteric artery ). It ends in a bifurcation into the left and right common iliac arteries. At the point of the bifurcation, there also springs a smaller branch, the median sacral artery.

Where does the aorta get its blood?

Its small branches supply blood to the ribs and some chest structures. • The abdominal aorta begins at the diaphragm, splitting to become the paired iliac arteries in the lower abdomen. Most of the major organs receive blood from branches of the abdominal aorta. Like all arteries, the aorta's wall has several layers:

How does the heart pump blood into the aorta?

The heart pumps blood from the left ventricle into the aorta through the aortic valve. Three leaflets on the aortic valve open and close with each heartbeat to allow one-way flow of blood. The aorta is a tube about a foot long and just over an inch in diameter. The aorta is divided into four sections:

How is aorta grafting done?

This is usually done through an incision in the abdomen. Aorta grafting (endograft): A damaged part of the aorta may be surgically replaced or reinforced with synthetic mesh. Aortic valve replacement: A damaged aortic valve may be surgically replaced, usually for aortic stenosis.

What is the probe placed on the chest?

Transthoracic echocardiogram: A probe placed on the chest projects ultrasound waves off the aorta and heart. The breastbone (sternum) obstructs clear ultrasound views of the aorta during transthoracic echocardiograms.

What causes shortness of breath and chest pain?

Rheumatic fever is the most common cause of aortic stenosis, which can cause chest pain or shortness of breath. Coarctation of the aorta: Narrowing of the aorta between its branches to the arms and those to the legs. This birth defect causes heart strain due to high blood pressure in the upper body.

What is the name of the condition where blood regurgitates backwards?

Aortic regurgitation: Another name for aortic insufficiency. Blood regurgitates backward through the incompletely closed aortic valve and into the heart's left ventricle. Aortic stenosis: Narrowing of the aortic valve, which causes the heart to strain to pump blood through.

What causes aortic insufficiency?

Aortic insufficiency: The aortic valve does not close completely, allowing some blood to flow back into heart with each beat. Conditions including autoimmune diseases, Marfan's syndrome, and endocarditis can cause aortic insufficiency. Aortic regurgitation: Another name for aortic insufficiency.

Major Blood Vessels

The circulatory system represents an essential component of human physiology that is responsible for carrying gases, nutrients, and other molecules throughout the body while simultaneously removing waste products. In addition, the circulatory system helps to maintain homeostasis within the body by regulating body temperature.

Aorta Branches

The largest artery in the human body is the aorta. The aortic artery location arises from the left ventricle of the heart and forms an arch that descends behind the heart and into the abdominal region.

Thoracic Aorta

The thoracic cavity represents the space located in the chest region between the neck and the diaphragm in humans. Parts of the aorta, including the ascending aorta, aortic arch, and descending aorta (also referred to as the thoracic aorta) branch off from the portion of the aorta located in the thoracic cavity.

What is the section of the aorta that runs through the abdomen called?

Aneurysms that occur in the section of the aorta that runs through the abdomen (abdominal aorta) are called abdominal aortic aneurysms.

What is the Aorta Center?
