QuestionChoice
The image shows an axial section through the upper level of the thorax – the apical regions of the lungs are visible, as is the trachea, which is located centrally. The oesophagus is located centrally at this level in the thorax (similarly to the trachea). It is a muscular tube which has a folded appearance when food is not present. It can be found posteriorly to the trachea. However, the arrow indicates the superior vena cava, which is situated to the right side of the trachea and it can be identified by the thin walls as a vein.

Superior vena cava
QuestionChoice
The image shows an axial section through the upper level of the thorax – the apical regions of the lungs are visible, as is the trachea located centrally. The pulmonary trunk is one of the vessels emerging from the right ventricle. As the heart is not visible in the dissected specimen, the pulmonary trunk cannot be visualised. However, the arrow indicates the superior vena cava, which is situated to the right side of the trachea and it can be identified by the thin walls as a vein.

Pulmonary trunk
QuestionChoice
The image shows an axial section through the upper level of the thorax – the apical regions of the lungs are visible, as is the trachea located centrally. The inferior vena cava is not visible at this high level in the thorax – it would become visible if the heart (Specifically the right atrium into which is drains blood would be visible). However, the arrow indicates the superior vena cava, which is situated to the right side of the trachea and it can be identified by the thin walls as a vein.
