Which body area includes breasts and axilla?

• A. Abdomen
• B. Chest
• C. Neck
• D. Back

Answer: (B)

The chest area is the front part of the torso between the neck and the abdomen. It includes the pectoral region where the breasts sit and the axilla (armpit) on the lateral chest wall. Because both structures lie on or near the anterior chest wall, the chest is the correct region that includes both breasts and axilla. The abdomen is below the chest, the neck is above, and the back is the posterior surface.
