Which term studies the body by organ systems such as digestion, circulation, and respiration?

• A. Regional Anatomy
• B. Systemic Anatomy
• C. Gross Anatomy
• D. Histology

Answer: (B)

Systemic anatomy studies the body by organ systems, examining how each system functions and how they interact—such as the digestive, circulatory, and respiratory systems. That focus exactly matches the idea of studying the body through its organ systems, which is why it’s the best fit here. Regional anatomy would group structures by location (like abdomen or thorax) rather than by function, histology looks at tissues under a microscope, and gross anatomy is a broad term for anatomical study of structures visible to the naked eye without specifying a system-based approach.
