Curved portion , thoracic aorta and abdominal 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.
abdominal aorta The Abdominal aorta is the longest section of the aorta, beginning at the diaphragm and spanning the abdominal cavity. The Thoracic and abdominal aorta together make up the descending aorta.
abdominal aorta is the portion of the descending aorta inferior to the diaphragm. it passes thru a hole in the diaphragm called aortic hiatus
The descending aorta.The aorta is divided in ascending, aortic arch, descending, thoracic, and abdominal.
There are actually more than one portion of the aorta that is in the abdominopelvic cavity. The left ventricle and thoracic aorta of the heart lead to the abdominal aorta which begins at the diaphragm. The abdominal aorta first branches into the inferior phrenic and celiac arteries, superior mesenteric and middle suprarenal arteries, renal and gonadal arteries, lumbar artery, inferior mesenteric artery, and the median sacral and common iliac arteries. From there, the artery splits to form the two common iliac arteries that carry blood to the legs.
Ascending simply means that "x" originates at a lower point than it terminates. For example, the ascending aorta starts from the left ventricle and ends at the arch of the aorta. The left ventricle is inferior to the arch of the aorta, thus that portion of the aorta is considered ascending.
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.
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.
Terminal Portion of the Large Intestine.
This is hard to answer with the way you ask. We have tha aorta coming out of the heart, then the brachiocephalic, left common carotic, and right subclavian artery coming off that. If you are asking which is at top, well that's still hard to answer, but I would say the brachiocephalic. That splits into the right subclavian and right common carotid arery.
Rate is equal to portion divided by base
The largest vessel attached to the heart is the Aorta, and it is responsible for delivering blood to the body. It is categorized in 2 groups, the Ascending Aorta and the Descending Aorta. The Ascending aorta includes the Carotid Arteries, which deliver blood to the brain, and the Subclavian Arteries, which brings blood to the arms. The Descending Aorta is located in the thoracic cavity with the rest of the heart and Aorta and is the part of the Aorta that curves down toward the bottom of the body and branches off into other arteries which supply the bottom portion of the body with blood.
