The ascending aorta extends from the aortic root (which connects the aorta to the heart), upwards toward the aortic arch.
The thoracic aorta is one of two parts of the descending aorta, which extends back down towards the abdomen after the aortic arch.
The thoracic aorta is the part of the descending aorta that is above the diaphragm, while the abdominal aorta is below the diaphragm.

What are the subdivisions of the aorta?
The aorta is one vessel that can be conceptualized in six parts: The aortic root: connects the aorta to the left ventricle. The coronary arteries emerge from this part. Ascending aortia: Moving away from the heart towards the neck. Aortic arch: the aorta turns at this point to descend towards the rest of the body. Branches to the brain and upper extremities branch away here. Descending aorta: extends down the back and divides into the common iliac arteries. The portion above the diaphragm is the thoracic aorta, the portion below the diagram is the abdominal aorta.
What divides the aorta into a superior thoracic aorta and an inferior abdominal aorta?
The diaphragm divides the aorta into a superior thoracic aorta above the diaphragm and an inferior abdominal aorta below the diaphragm.
What is ectatic ascending aorta?
If its dilated up to 3 cm, seems to be a precursor condition to distended (swollen) condition which is a precursor to a ruptured aorta Usually occurs in the descending (or abdominal) aorta.
What is the normal range of the size of the aorta?
The normal range for the size of the aorta is typically between 2 to 3 centimeters in diameter for the ascending aorta, 2 to 2.5 centimeters for the arch, and 1.5 to 2 centimeters for the descending aorta. These measurements can vary depending on age, gender, and body size.
The entrance to the ascending aorta is guarded by the valve?
The entrance to the ascending aorta is guarded by the aortic valve. It ensures that blood flows from the left ventricle into the aorta and prevents backflow into the heart. The aortic valve opens during ventricular contraction and closes to prevent blood from flowing back into the heart during ventricular relaxation.
What body cavity is the ascending aorta found?
Ascending aorta, arch of aorta and the descending aorta are located in your thoracic cavity.
What is the name of the missing artery between the ascending aorta and descending thoracic aorta?
The Arch, but is not missing anyway
What are the 4 parts of the aorta?
The aorta consists of : the ascending aorta, the arch of the aorta, the thoracic portion of the descending aorta, and the abdominal portion of the descending aorta.
What are the four principle divisions of the aorta?
ascending aorta arch of aorta thoracic aorta abdominal aeorta
What is the anatomical difference between the thoracic aorta and femoral artery?
Elastic fibres
Name all of the different sections of the aorta?
Ascending, arch, descending thoracic and abdominal
What aorta turns inferiorly behind the heart?
The descending aorta.The aorta is divided in ascending, aortic arch, descending, thoracic, and abdominal.
What are the subdivisions of the aorta?

What divides the aorta into a superior thoracic aorta and an inferior abdominal aorta?
The diaphragm divides the aorta into a superior thoracic aorta above the diaphragm and an inferior abdominal aorta below the diaphragm.
What is the function of the ascending aorta?
The ascending aorta delivers oxygenated blood FROM the heart, TO the head and arms.
What divides the thoracic aorta from the inferior abdominal aorta?
The diaphragm divides the thoracic and abdominal aorta. These are both parts of the descending aorta, extending from the aortic arch.
What is ectatic ascending aorta?
If its dilated up to 3 cm, seems to be a precursor condition to distended (swollen) condition which is a precursor to a ruptured aorta Usually occurs in the descending (or abdominal) aorta.
