Histology is the study of which of the following?

• A. Tissues
• B. Organs
• C. Cells
• D. Systems

Answer: (A)

Histology focuses on the microscopic structure of tissues—the organized grouping of cells and the extracellular matrix that form tissue. This makes tissues the best answer because organs are built from tissues, systems are groups of organs, and cytology studies individual cells. By using tissue sections and special stains, histology reveals how cells come together to create tissue types (like epithelial, connective, muscular, and nervous tissue) and how those tissues arrange to make up organs. So, the study is about tissues, not the whole organs, systems, or isolated cells.
