QuestionChoice
The image shows an axial section through the middle area of the thorax – at the level of the vessels emerging superiorly from the heart. The ascending aorta is located anteriorly to the structure indicated by the arrow and it has a muscular circular lumen. The arrow indicates the right pulmonary artery, which arises from the pulmonary trunk.

Ascending aorta
QuestionChoice
The image shows an axial section through the middle area of the thorax – at the level of the vessels emerging superiorly from the heart. The pulmonary trunk and its bifurcation into the left and right pulmonary arteries can be visualised. The inferior pulmonary veins are much smaller in diameter compared to the vessel indicated by the arrow, which is the right pulmonary artery.

Inferior pulmonary veins
QuestionChoice
The image shows an axial section through the middle area of the thorax – at the level of the vessels emerging superiorly from the heart. The pulmonary trunk and its bifurcation into the left and right pulmonary arteries can be visualised. The arrow indicates the right, not the left pulmonary artery – because the section is as if one is looking inside the patient from below (where the legs are).

b
Left pulmonary artery
QuestionChoice
The image shows an axial section through the thorax – at the level of the vessels emerging superiorly from the heart. The pulmonary trunk and its bifurcation into the left and right pulmonary arteries can be visualised. The arrow indicates the right pulmonary artery.
