What does histology study?

Body systems
Cell functions
Tiny structures visible through a microscope
Organic chemicals

The correct answer is: Tiny structures visible through a microscope

Histology is the study of tissues, which are made up of cells and surrounding extracellular matrix. This option is correct because tiny structures are visible through a microscope to study tissues and their structure. Option A is incorrect because it is broader and encompasses the study of entire body systems, not just tissues. Option B is incorrect because cell functions are studied in cell biology, not histology. Option D is incorrect because histology focuses on tissues, not organic chemicals.
