Question: Why doesn't the Superior Vena Cava get as much press as the Aorta!?

Answers:
Superior vena cava drains the blood from the upper part of the body to the heart!. Inferior vena cava drains blood from the lower part of the body into the heart!. Coronary sinus drains blood from the vessels supplying the heart into the right atrium of the heart!. So there are three vessels returning blood to the heart and all of them operate at low pressure as it is a passive process!.

Aorta carries blood to the whole of the body including the heart and it works at high pressure as blood is actively pumped into it by the heart!. A tear in the aorta is far more dangerous than a tear in any of the other vessels, even though tear in any vessel can be dreadful!.Www@Answer-Health@Com

if i remember my biology well, vena cava only directs blood to the lungs but the aorta needs to pump to the whole body!.Www@Answer-Health@Com
