Question 1
Which of the following is the study of the function of the human body?
,A) Anatomy
B) Histology
C) Physiology
D) Cytology
Answer: C
Rationale: Physiology is the study of the function of the human body, while anatomy is the
study of its structure. Histology is the study of tissues, and cytology is the study of cells.
The principle of complementarity states that structure determines function, linking these
two branches of science.

Question 2
What is the correct order of the levels of structural organization in the human body, from
simplest to most complex?
A) Chemical → Cellular → Tissue → Organ → Organ System → Organismal
B) Cellular → Chemical → Tissue → Organ → Organ System → Organismal
C) Chemical → Tissue → Cellular → Organ → Organ System → Organismal
D) Tissue → Cellular → Chemical → Organ → Organ System → Organismal
Answer: A
, Rationale: The levels of structural organization, from simplest to most complex, are:
Chemical → Cellular → Tissue → Organ → Organ System → Organismal. Atoms combine to
form molecules, which combine to form cells. Cells combine to form tissues, which
combine to form organs. Organs work together to form organ systems, which combine to
make up an organism.
---
Question 3
Organization, metabolism, responsiveness, movement, development, growth, and
reproduction all together are called __________ of a human body.
A) Catabolism
B) Anabolism
C) Anatomy
D) Functions
E) Structures
Answer: D
Rationale: These are the essential functions or characteristics of life in the human body.
Catabolism and anabolism are specific metabolic processes. Anatomy refers to structure.
