Which statement best describes the relationship between anatomy and physiology?

• A. Anatomy focuses on the function of body parts, while physiology studies their structure.
• B. Anatomy and physiology are unrelated fields that study different aspects of biology.
• C. Anatomy and physiology are both concerned with the chemical processes within the body.
• D. Anatomy is the study of the structure of body parts, while physiology is the study of how these parts function.

Answer: (D)

Verified step by step guidance

1. Begin by understanding the definitions of anatomy and physiology. Anatomy is the branch of science concerned with the bodily structure of humans, animals, and other living organisms, especially as revealed by dissection and the separation of parts. Physiology, on the other hand, is the branch of biology that deals with the normal functions of living organisms and their parts.
2. Recognize that anatomy and physiology are complementary fields. While anatomy provides information about the structure and location of body parts, physiology explains how these parts work and interact with each other to sustain life.
3. Consider the relationship between structure and function. In anatomy, you might study the heart's chambers and valves, while in physiology, you would explore how the heart pumps blood and maintains circulation.
4. Understand that anatomy and physiology are often taught together because knowing the structure of a body part helps in understanding its function, and vice versa. For example, the structure of the lungs (anatomy) is directly related to their function in gas exchange (physiology).
5. Conclude that the correct statement is: Anatomy is the study of the structure of body parts, while physiology is the study of how these parts function. This highlights the interdependent nature of these two fields in understanding the human body.
