Cytology is the study of:

• A. Studies tissues of the body.
• B. Studies cells of the body.
• C. Studies organs.
• D. Studies body systems.

Answer: (B)

Cells are the basic units of life, and cytology is the study of those cells—their structure, organelles, and life processes. By examining cells under a microscope, you learn how they look when healthy and how they change in disease, such as in Pap smears or blood smears. This is distinct from histology, which focuses on tissues—the organized groups of cells that form functional units. Organs come from tissues, and body systems are made up of multiple organs. So, cytology is specifically about studying the cells themselves.
