• C. Medial
• D. Lateral

Answer: (C)

Verified step by step guidance

1. Step 1: Begin by understanding the directional terms used in anatomy. Directional terms are used to describe the location of one body structure relative to another. For example, 'medial' refers to a position closer to the midline of the body, while 'lateral' refers to a position farther from the midline.
2. Step 2: Identify the anatomical location of the heart and lungs. The heart is located in the thoracic cavity, near the center of the chest, while the lungs are positioned on either side of the heart.
3. Step 3: Compare the position of the heart relative to the lungs. Since the heart is closer to the midline of the body and the lungs are located laterally (on the sides), the heart is described as being 'medial' to the lungs.
4. Step 4: Eliminate other directional terms that do not apply. For example, 'distal' refers to a position farther from the point of attachment or origin, which is not relevant here. 'Superficial' refers to a position closer to the surface of the body, which also does not apply in this context.
5. Step 5: Conclude that the correct directional term to describe the position of the heart relative to the lungs is 'medial,' as it accurately reflects the heart's location closer to the midline of the body compared to the lungs.
