Pathology is the study of which of the following?

• A. The blood supply to tissues
• B. Tissue to check for disease
• C. The nervous system
• D. The endocrine system

Answer: (B)

Pathology centers on disease, using tissue and cellular changes to understand what went wrong in the body. It explores how diseases start and progress, what structural changes they cause in tissues, and how those changes help diagnose illness. The option that describes studying tissue to check for disease is best because it captures the core activity of pathology: examining tissue to identify abnormal changes that indicate disease. The other choices point to normal anatomy or to specific body systems, which are not the defining focus of pathology itself.
