The study of the human body structures seen with the naked eye is known as what?

1. Anatomy

2. Histology

3. Cytology

4. Protoplasm

The correct answer is: Anatomy

The study of human body structures that can be observed without the aid of a microscope is referred to as anatomy. This branch of biology focuses on understanding the physical structures of organisms, including their organs, tissues, and systems. Anatomy can be divided into several sub-disciplines, such as gross anatomy, which entails the examination of structures visible to the naked eye, and regional anatomy, which looks at specific areas of the body. In contrast, histology is the study of microscopic structures within tissues, requiring a microscope for examination. Cytology focuses even more narrowly on the study of individual cells, including their structure, function, and chemistry. Protoplasm refers to the living content of a cell that is surrounded by a plasma membrane, encompassing both the cytoplasm and the nucleus, but it is not a term that describes the study of body structures. Thus, anatomy is the most accurate term for the study of visible body structures.
