What is the function of a aorta?
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 does the aorta do quizlet?
Largest arterial structure in the body, arises from the left ventricle of the heart and supply blood to the head, upper & lower extremity.
What is the function of aorta and branches?
The aorta is divided into four sections: The ascending aorta rises up from the heart and is about 2 inches long. The coronary arteries branch off the ascending aorta to supply the heart with blood. The aortic arch curves over the heart, giving rise to branches that bring blood to the head, neck, and arms.
What happens if the aorta is damaged?
Sudden severe chest or upper back pain, often described as a tearing or ripping sensation, that spreads to the neck or down the back. Sudden severe stomach pain. Loss of consciousness. Shortness of breath.
What causes weak aorta?
Hardening of the arteries (atherosclerosis). As plaque builds up on your artery walls, they become less flexible, and the additional pressure can cause them to weaken and bulge. High blood pressure and high cholesterol are risk factors for hardening of the arteries. This is more common in older people.
What are the five sections of the aorta?
Anatomy of the Aorta
- Aortic Root. The aortic root is the portion of the aorta that is attached to the heart.
- Ascending Aorta.
- Aortic Arch.
- Descending Thoracic Aorta.
- Abdominal Aorta.

What would cause an 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.
Why is aortic pressure high?
The rise in aortic pressure from its diastolic to systolic value is determined by the compliance of the aorta as well as the ventricular stroke volume. In the arterial system, the aorta has the highest compliance, due in part to a relatively greater proportion of elastin fibers versus smooth muscle and collagen.
What is the aorta, and what is the main function?
– Atherosclerosis, or the hardening of the heart – Aortic arch syndrome, a group of symptoms that are linked to structural problems with the arteries that branch off from the aorta – Aortic birth defects – Coartacation of the aorta (narrowing of the aortic arch) – Takayasu’s arteritis, which can cause stroke, heart attack, or other damage
What is the purpose of the aorta?
Abstract. Resuscitative endovascular balloon occlusion of the aorta (REBOA) for rapid hemorrhage control is increasingly being used in trauma management.
What does aorta do in the circulatory system?
– Distributes OXYGEN as well as eliminates Co2. – Gives cells with NUTRIENTS. – Gets Rid Of the waste items of metabolic process to the purgative body organs for disposal. – Safeguards the body versus illness as well as infection. – Thickening quits hemorrhaging after injury.
