Aorta vs. Artery — What's the Difference?
Edited by Tayyaba Rehman — By Fiza Rafique — Updated on September 27, 2023
The Aorta is the body's main and largest artery, originating from the heart, while an Artery is any of the muscular-walled tubes that carry blood from the heart to other parts of the body.

Key Differences
The Aorta and Artery are integral components of the circulatory system, but they serve different roles and possess distinguishing features. The Aorta is a singular entity, the principal artery departing from the heart, channeling oxygen-rich blood to the body. In contrast, the term Artery refers to a system of numerous vessels that perform a similar function on a broader scale, distributing blood throughout the body.
Every Artery in the body, regardless of its size or location, is tasked with conveying oxygenated blood away from the heart. The Aorta, specifically, is the inception of this arterial system, branching out to become smaller arteries, which then further subdivide into arterioles and capillaries.
One could analogize the Aorta to a major highway, providing the primary route for traffic, while an Artery could be any roadway or street stemming from that highway. The Aorta, with its vast diameter and strategic placement, plays a pivotal role in the hemodynamics of circulation, while each Artery contributes to ensuring that every bodily tissue receives the vital oxygen and nutrients it requires.

Compare with Definitions
Aorta
The starting point of systemic circulation.
Blood ejected from the left ventricle enters the Aorta to be distributed throughout the body.
Artery
Essential for transporting oxygenated blood.
Each Artery ensures tissues receive the oxygen they need.
Aorta
Susceptible to conditions like aneurysms.
Regular screenings can help detect abnormalities in the Aorta early on.
Artery
A vessel carrying blood away from the heart.
The carotid Artery supplies blood to the brain.
Aorta
A vessel that branches into various major arteries.
The Aorta bifurcates into the thoracic and abdominal aorta.
Artery
Walls are muscular and elastic.
The elasticity of an Artery allows it to withstand the pressure of blood flow.
Aorta
The primary artery stemming from the heart.
The Aorta begins at the left ventricle and extends to the abdomen.
Artery
An artery (plural arteries) (from Greek ἀρτηρία (artēríā) 'windpipe, artery') is a blood vessel that takes blood away from the heart to one or more parts of the body (tissues, lungs, brain etc.). Most arteries carry oxygenated blood; the two exceptions are the pulmonary and the umbilical arteries, which carry deoxygenated blood to the organs that oxygenate it (lungs and placenta, respectively).
Aorta
The largest artery in the human body.
Due to its size, the Aorta plays a significant role in systemic circulation.
Artery
Any of the muscular-walled tubes forming part of the circulation system by which blood (mainly that which has been oxygenated) is conveyed from the heart to all parts of the body.
Aorta
The aorta ( 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). The aorta distributes oxygenated blood to all parts of the body through the systemic circulation.
Artery
An important route in a system of roads, rivers, or railway lines
George Street, main artery of Edinburgh's Golden Mile
Aorta
The main trunk of the systemic arteries, carrying blood from the left side of the heart to the arteries of all limbs and organs except the lungs.
Artery
(Anatomy) Any of the muscular elastic tubes that form a branching system and that carry blood away from the heart to the cells, tissues, and organs of the body.
Aorta
(anatomy) The great artery which carries the blood from the heart to all parts of the body except the lungs; the main trunk of the arterial system.
Artery
A major route of transportation into which local routes flow
Traffic was heavy on the central artery.
Aorta
(figuratively) The liveliest part of something.
Artery
(anatomy) Any of the muscular- and elastic-walled blood vessels forming part of the circulation system by which blood is conveyed away from the heart regardless of its oxygenation status; see pulmonary artery.
Aorta
The great artery which carries the blood from the heart to all parts of the body except the lungs; the main trunk of the arterial system.
Artery
(transport) A major transit corridor in a system of roads, rivers, or railway lines.
Aorta
The large trunk artery that carries blood from the left ventricle of the heart to branch arteries
Artery
The trachea or windpipe.
Artery
One of the vessels or tubes which carry either venous or arterial blood from the heart. They have tricker and more muscular walls than veins, and are connected with them by capillaries.
Artery
Hence: Any continuous or ramified channel of communication; as, arteries of trade or commerce.
Artery
A blood vessel that carries blood from the heart to the body
Artery
A major thoroughfare that bears important traffic
Artery
Part of the vast arterial network in the body.
Damage to an Artery can impede blood flow to certain regions.
Artery
Can branch into arterioles and capillaries.
The radial Artery in the arm is palpable near the wrist.
Common Curiosities
What is the main difference between an Artery and a vein?
An Artery carries oxygenated blood (except for the pulmonary artery), while a vein carries deoxygenated blood.
What is the Aorta's primary function?
The Aorta distributes oxygen-rich blood from the heart to the rest of the body.
Are veins and Arteries the same?
No, Arteries carry blood away from the heart, while veins bring blood back to the heart.
How many Arteries does the human body have?
The body has numerous Arteries that branch into smaller arterioles and capillaries.
What happens if the Aorta gets blocked?
A blockage in the Aorta can be life-threatening and requires immediate medical intervention.
Why are Artery walls thick and muscular?
Artery walls are thick to withstand the high pressure of blood pumped from the heart.
Can the Aorta develop medical conditions?
Yes, the Aorta can suffer from issues like aneurysms or dissections.
Where does the Aorta originate?
The Aorta arises from the left ventricle of the heart.
Is the Aorta considered an Artery?
Yes, the Aorta is the largest Artery in the body.
What's the main difference between the Aorta and other Arteries?
The Aorta is the primary artery from the heart, while other Arteries branch from it or other major arteries.
Can an Artery be repaired if damaged?
Yes, surgical procedures can repair or bypass damaged Arteries.
How important is the Aorta in circulation?
Extremely important; the Aorta is central to systemic circulation.
Do all Arteries carry oxygen-rich blood?
Most do, but the pulmonary Artery carries deoxygenated blood to the lungs.
Why is the Aorta's health crucial?
Given its role in circulation, Aorta health is vital for overall bodily function.
