The entrance to the ascending aorta is guarded by the semilunar valve. The semilunar valves are pocketlike structures attached at the point at which the pulmonary artery and the aorta leave the ventricles.

What valve is at the entrance to the aorta?
The heart pumps blood from the left ventricle through the aortic semilunar valve into the Aorta.
Which aorta pump blood to left ventricle ascending aorta or descending aorta?
Blood goes in this order... Right Atrium -> Right Ventricle -> Lungs -> Left Atrium -> Left Ventricle -> Ascending Aorta -> Descending Aorta. So neither pump blood to the the Left Ventricle but the Left Ventricle pumps blood to the ascending aorta.
What is the name of the missing artery between the ascending aorta and descending thoracic aorta?
The Arch, but is not missing anyway
Do you have two aortas in your body?
No. No doubt you r confusion lies with the fact that there is the ascending aorta and the descending aorta. This is similar to the colon in that actually it is one continuouus thing. The ascending aorta leaves the left ventricle travelling upwards but very quickly becomes the aortic arch, looping down to form the descending aorta.
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.
The entrance to the ascending aorta is guarded by the valve?
semilular valve
What guards the entrance to the ascending aorta?
the aortic semilunar valve
What valve is at the entrance to the aorta?
The heart pumps blood from the left ventricle through the aortic semilunar valve into the Aorta.
What is the function of the ascending aorta?
The ascending aorta delivers oxygenated blood FROM the heart, TO the head and arms.
What body cavity is the ascending aorta found?
Ascending aorta, arch of aorta and the descending aorta are located in your thoracic cavity.
What are the four principle divisions of the aorta?
ascending aorta arch of aorta thoracic aorta abdominal aeorta
Which aorta pump blood to left ventricle ascending aorta or descending aorta?
Blood goes in this order... Right Atrium -> Right Ventricle -> Lungs -> Left Atrium -> Left Ventricle -> Ascending Aorta -> Descending Aorta. So neither pump blood to the the Left Ventricle but the Left Ventricle pumps blood to the ascending aorta.
What does asending mean?
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.
What blood vessel supplies the descending aorta with blood?
blood travels from the ascending aorta to the aortic arch to the descending aorta
What blood vessel is proximal to the heart?
ascending aorta
What is the difference between the ascending aorta and the thoracic 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.
What is the name of the missing artery between the ascending aorta and descending thoracic aorta?
The Arch, but is not missing anyway
