,BIOS 251 Exam 1 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. While the other options describe
functions, they do not as clearly illustrate the direct structure-function
relationship.
**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.** Which level of organization consists of two or more different types of
tissues that work together to perform a specific function?
A) Chemical level
B) Cellular level
C) Organ level
D) System level
**Correct Answer:** C) Organ level
