Verified step by step guidance

Understand the directional terms: 'Medial' refers to a position closer to the midline of the body, while 'Lateral' refers to a position farther from the midline. 'Superior' means above, and 'Distal' refers to a position farther from the point of attachment or origin.

Identify the anatomical location of the heart and lungs: The heart is located in the thoracic cavity, specifically in the mediastinum, which is near the midline of the body. The lungs are positioned on either side of the heart.

Compare the position of the heart relative to the lungs: Since the heart is closer to the midline of the body compared to the lungs, the term 'Medial' is appropriate to describe its position.

Eliminate incorrect options: 'Distal' is not relevant here as it refers to distance from a point of attachment. 'Lateral' is incorrect because the heart is not farther from the midline than the lungs. 'Superior' is also incorrect because the heart is not above the lungs.

Conclude that the correct directional term to describe the position of the heart relative to the lungs is 'Medial'.
