descending aorta
You most likely mean the aorta.
A tortuous thoracic aorta is an aorta that is twisted or misshapen in some people. This can lead to discomfort in some people, but no effects at all in others.
The Arch, but is not missing anyway
The aorta is the main artery that takes blood from the heart to the body. The aorta drains the left atrium.

A very simplistic explanation: If we start with the aorta (the biggest artery in the body), the oxygenated blood from the heart travels through this around the entire body and supplies oxygen, nutrients, etc. The deoxygenated blood then travels back to the heart via the venous systems and enters the left atrium. From the left atrium it travels to the left ventricle and is pumped by this ventricle through the pulmonary arteries (don't be deceived by the name here - the blood is still deoxygenated), to the lungs where it picks up oxygen. The oxygenated blood then travels back to the heart through the pulmonary veins and enters the right atrium. It then travels into the right ventricle and the ventricle pumps the blood into the aorta and the cycle repeats. Essentially you have two closed loops.
