Tattooing is performed into which body system?

• A. Nervous system
• B. Digestive system
• C. Integumentary system
• D. Circulatory system

Answer: (C)

Tattooing targets skin tissue, which is part of the integumentary system. The pigment is placed into the dermal layer of the skin, not into other body systems. The nervous system governs sensation in the skin, the digestive system handles digestion, and the circulatory system involves blood flow but is not the tissue being modified by the procedure. Since the primary tissue involved is skin, the correct system is the integumentary system.
