QuestionChoice
The image shows a dissection of the posterior view of the thorax, with the vertebral column in the midline. The arrow points to the hemiazygous vein, which runs in the posterior mediastinum, to the left of the vertebral column, draining into the azygous vein on the right side at the level of T8. Its main function is to drain venous blood from the left side of the posterior thoracic wall, collecting blood from the posterior intercostal veins. This answer is not correct because it refers to the right, instead of the left side.

c
Drains venous blood from the posterior intercostal veins of the right side of the thorax and abdomen

The image shows a dissection of the posterior view of the thorax, with the vertebral column in the midline. The arrow points to the hemiazygous vein, which runs in the posterior mediastinum, to the left of the vertebral column, draining into the azygous vein on the right side at the level of T8. Its main function is to drain venous blood from the left side of the posterior thoracic wall.

a
Drains venous blood from the left hemithorax
QuestionChoice
The image shows a dissection of the posterior view of the thorax, with the vertebral column in the midline. The arrow points to the hemiazygous vein, which runs in the posterior mediastinum, to the left of the vertebral column, draining into the azygous vein on the right side at the level of T8. Its main function is to drain venous blood from the left side of the posterior thoracic wall. The lymphatic drainage of the left superior half of the body is achieved by the right lymphatic duct.

e
Drains lymph from the right half of the upper body
QuestionChoice
The image shows a dissection of the posterior view of the thorax, with the vertebral column in the midline. The arrow points to the hemiazygous vein, which runs in the posterior mediastinum, to the left of the vertebral column, draining into the azygous vein on the right side at the level of T8. Its main function is to drain venous blood from the left side of the posterior thoracic wall. Because it is a vein, not an artery, the function of supplying blood to the left side of the thoracic cavity wall is not correct.

b
Supplies blood to the left hemithorax
QuestionChoice
The image shows a dissection of the posterior view of the thorax, with the vertebral column in the midline. The arrow points to the hemiazygous vein, which runs in the posterior mediastinum, to the left of the vertebral column, draining into the azygous vein on the right side at the level of T8. Its main function is to drain venous blood from the left side of the posterior thoracic wall. The lymphatic drainage of the left superior half of the body is achieved by the thoracic duct, which also collects lymph from the inferior aspect of the body.
