Question

Aorta goes behind the heart at level of __
A. T6
B. T8
C. T10
D. T12

Answer 1

The aorta moves in a superior direction, forms an arc called the aortic arch, and then descends towards the inferior portions of the body at the level of T4-T5 vertebrae. The abdominal aorta terminates at the level of the fourth lumbar vertebra where it bifurcates into the two common iliac arteries.

Step-by-step explanation:

The ascending aorta moves in a superior direction for approximately 5 cm and ends at the sternal angle. Following this ascent, it reverses direction, forming a graceful arc to the left, called the aortic arch. The aortic arch descends toward the inferior portions of the body and ends at the level of the intervertebral disk between the fourth and fifth thoracic vertebrae. Beyond this point, the descending aorta continues close to the bodies of the vertebrae and passes through an opening in the diaphragm known as the aortic hiatus.

Superior to the diaphragm, the aorta is called the thoracic aorta, and inferior to the diaphragm, it is called the abdominal aorta. The abdominal aorta terminates when it bifurcates into the two common iliac arteries at the level of the fourth lumbar vertebra.

Answer 2

The aorta goes behind the heart at the level of T8.

Step-by-step explanation:

The aorta goes behind the heart at the level of T8. The aorta is the largest artery in the body and provides blood to virtually all tissues of the body. It arises from the left ventricle of the heart and descends to the abdominal region, where it bifurcates into the two common iliac arteries at the level of the fourth lumbar vertebra.
