Question

which of the following best defines anatomy?
○ it is the study of how the body parts work and carry out their life-sustaining activities.
○ it is the study of tissues.
○ it is the study of all chemical reactions that occur within body cells.
○ it is the study of the structure of body parts and their relationships with one another.

Explanation:

• The first option describes physiology (study of function), not anatomy.
• The second option (study of tissues) is histology, not anatomy.
• The third option describes biochemistry (chemical reactions in cells), not anatomy.
• The fourth option correctly defines anatomy as the study of the structure of body parts and their relationships.

Answer:

D. It is the study of the structure of body parts and their relationships with one another. (Note: Assuming the last option is D; if the options were labeled differently, adjust the label but keep the description. Since the original options' labels aren't shown with letters here but the last option is the correct one, we identify it as the correct definition of anatomy.)
