The correct answer is A. A doctor would focus on the thoracic region while examining a patient for lung disease.
Explanation:
The thorax is the part of the human body that is between the base of the neck and the abdomen, from which it is separated by the diaphragm. It contains the lungs and mediastinum. It is shaped like half a tonne and its wall is made up of ribs and intercostal muscles on its sides, which connect anteriorly to the sternum and behind to the dorsal spine. It constitutes an osteocartilaginous box called the rib cage or thoracic cavity. It contains the lungs, heart, large blood vessels such as the aorta (ascending, arching and descending) arteries, the inferior vena cava, the sympathetic ganglion chain where the splanchnic nerves come from, and the esophagus. The mediastinum represents the median space of the rib cage.
The function of this "box" is to protect the internal organs from mechanical trauma that could otherwise injure them. The ribcage has the peculiarity of being expanded to allow for inspiration.
