Correct Answer Left lung

The correct answer is - B) LEFT LUNG.

41% of the people answer left lung where as 42% answer Right Ventricle.

Apex of lungs extends into the neck 3 to 4 cm above the first rib. Lung bases are in direct contact with diaphragm. The mediastinal surface of each lung has a cardiac impression that accommodates the heart.

The heart is partially covered by the lungs. The apex is formed by the left ventricle & is covered by the left lung. It lies behind the 5th intercostal space on the level of left midclavicular line.

Right ventricle forms the anterior sternocostal surface of the heart & lies medially to the left midclavicular line.

Left atrium is located posterior to the left ventricle & forms the base of the heart.

Therefore, a penetrating injury in the fifth intercostal space at the left midclavicular line would most likely injure the left lung!
