,BIOS 251 Final Exam Anatomy & Physiology I Questions And
Answers 2026/2027 Chamberlain
1.** Which of the following best defines **anatomy**?
A) The study of the function of body structures
B) The study of the structure of body parts and their relationships to one
another
C) The study of how body parts work together to maintain homeostasis
D) The study of disease processes in the body
**Correct Answer:** B) The study of the structure of body parts and their
relationships to one another
**Rationale:** Anatomy is the study of body structures and their physical
relationships. Physiology (A) is the study of function. Homeostasis (C) is the
maintenance of a stable internal environment.
**2.** Which of the following best defines **physiology**?
A) The study of the structure of body parts
B) The study of the function of body parts and how they interact
C) The study of disease processes
D) The study of the chemical composition of the body
**Correct Answer:** B) The study of the function of body parts and how they
interact
**Rationale:** Physiology is the study of how body parts function and
interact with one another. Anatomy (A) is the study of structure.
,**3.** The principle that structure and function are complementary is
illustrated by which of the following examples?
A) The heart has four chambers to pump blood efficiently
B) The brain controls voluntary movement
C) The skin provides a barrier to infection
D) The lungs exchange oxygen and carbon dioxide
**Correct Answer:** A) The heart has four chambers to pump blood
efficiently
**Rationale:** The heart's structure (four chambers) is directly related to its
function (efficient blood pumping). This illustrates the principle that structure
and function complement each other.
**4.** What is the basic structural and functional unit of life?
A) Tissue
B) Organ
C) Cell
D) Organ system
**Correct Answer:** C) Cell
**Rationale:** The cell is the smallest unit capable of independent life and
performs all vital functions. Tissues (A) are groups of cells; organs (B) are
groups of tissues; organ systems (D) are groups of organs.
, **5.** Which of the following lists the levels of organization in the human
body from simplest to most complex?
A) Cell, tissue, organ, organ system, organism
B) Tissue, cell, organ, organ system, organism
C) Organ, tissue, cell, organ system, organism
D) Cell, organ, tissue, organ system, organism
**Correct Answer:** A) Cell, tissue, organ, organ system, organism
**Rationale:** The levels of organization progress from the simplest (cells) to
the most complex (organism). Cells form tissues, tissues form organs, organs
form organ systems, and organ systems work together to form an organism.
**6.** A tendency for organisms to maintain a balanced or constant internal
state is called:
A) Equilibrium
B) Homeostasis
C) Metabolism
D) Homeostatic imbalance
**Correct Answer:** B) Homeostasis
**Rationale:** Homeostasis is the tendency of organisms to maintain a
balanced or constant internal state. Equilibrium (A) is a state of balance, but
homeostasis is the dynamic process of maintaining that balance.
