QuestionChoice
The image shows a dissected thorax. This answer describes the function of the descending aorta, which transports oxygenated blood from the left ventricle to the rest of the body. However, the arrow indicates the oesophagus, which passes anterior to the descending aorta from right to left. The descending aorta can be visualised just lateral to the oesophagus. The function of the oesophagus is to allow the passage of the food bolus from the oropharynx to the stomach.

b
Passage of oxygenated blood from left ventricle to the rest of the body
QuestionChoice
The image shows a dissected thorax. This answer describes the function of the inferior vena cava, which is not easily visible in this dissection. It normally lies to the right of the structure indicated by the arrow, which is the oesophagus. The function of the oesophagus is to allow the passage of the food bolus from the oropharynx to the stomach.

c
Drainage of venous blood from the lower half of the body to the right atrium
QuestionChoice
The image shows a dissected thorax. This answer describes the function of the thoracic duct, which is the main lymphatic vessel draining lymph from the inferior half of the body and from the left upper half of the body. The thoracic duct is located in the posterior mediastinum, posteriorly to the structure indicated by the arrow – the oesophagus. The function of the oesophagus is to allow the passage of the food bolus from the oropharynx to the stomach.

Drainage of lymph from the inferior half of the body and from the left upper half of the body
QuestionChoice
The image shows a dissected thorax. The arrow indicates the oesophagus, which is a muscular tube structure, which passes anterior to the descending aorta from right to left. The aorta can be visualised just lateral to the oesophagus. The function of the oesophagus is to allow the passage of the food bolus from the oropharynx to the stomach.

a
Passage of food bolus from the oropharynx to the stomach
QuestionChoice
The image shows a dissected thorax. This answer describes the function of the superior vena cava, which is located more superiorly compared to the level of the structure indicated by the arrow, which is the oesophagus. The function of the oesophagus is to allow the passage of the food bolus from the oropharynx to the stomach.
