circulatory system
The aorta is part of the circulatory system. It is the largest artery in the body and leads from the heart down through the abdomen and splits into smaller blood vessels that feed the lower half of the body (such as the femoral arteries).
blood travels from the ascending aorta to the aortic arch to the descending aorta
Ascending aorta, arch of aorta and the descending aorta are located in your thoracic cavity.
The aorta is a major artery and it is part of the cardiovascular system.
descending aorta
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
descending aorta
The descending aorta.The aorta is divided in ascending, aortic arch, descending, thoracic, and abdominal.
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.
If you are talking about where does the blood inside the descending aorta come from, it comes from the aortic arch, which comes from the ascending aorta. If you are talking about the blood that nourishes the tissues of the aorta, it is the vasa vasorum.
The aorta is usually divided into five segments/sections:Ascending aorta: the section between the heart and the arch of aortaArch of aorta-the peak part that looks somewhat like an inverted "U"Descending aorta-the section from the arch of aorta to the point where it divides into the common iliac arteriesThoracic aorta-the half of the descending aorta above the diaphragmAbdominal aorta-the half of the descending aorta below the diaphragm
