Which of the following terms correctly describes the position of the heart relative to the lungs?
A
Lateral
B
Medial
C
Distal
D
Superficial
Verified step by step guidance1
Understand the anatomical directional terms: 'Lateral' means away from the midline of the body, 'Medial' means toward the midline, 'Distal' refers to a point farther from the trunk or point of attachment, and 'Superficial' means closer to the surface of the body.
Visualize the anatomical position: The heart is located in the thoracic cavity, between the lungs, slightly to the left of the midline of the body.
Compare the position of the heart relative to the lungs: Since the heart is located closer to the midline of the body and the lungs are positioned on either side of the heart, the heart is medial to the lungs.
Eliminate incorrect options: 'Lateral' would mean the heart is farther from the midline, which is incorrect. 'Distal' refers to limbs and is not applicable here. 'Superficial' refers to being closer to the surface, which is also incorrect in this context.
Conclude that the correct term to describe the position of the heart relative to the lungs is 'Medial'.
