IVY TECH APHY 101 FINAL EXAM: ANATOMY AND
PHYSIOLOGY I, ACTUAL QUESTIONS AND 100%
CORRECT ANSWERS | LATEST UPDATED 2026/2027
(GRADED A+)
, AT IVY TECH COMMUNITY COLLEGE
Section 1: Introduction & Basic Concepts (Questions 1–25)
Q1. Which of the following best describes the relationship between anatomy
and physiology?
a) Anatomy studies function; physiology studies structure
b) Anatomy studies structure; physiology studies function
c) Anatomy and physiology are unrelated fields
d) Physiology only studies organ systems
Answer: b) Anatomy studies structure; physiology studies function
Rationale: Anatomy examines the physical structures of the body, such as organs an
d tissues. Physiology explains how those structures function. Both fields are interconne
cted because structure often determines function.
Q2. Which level of organization is correctly listed from simplest to most com
plex?
a) Organ → Tissue → Cell → Organ system → Organism
b) Cell → Tissue → Organ → Organ system → Organism
c) Tissue → Cell → Organ → Organ system → Organism
d) Organ system → Organ → Tissue → Cell → Organism
Answer: b) Cell → Tissue → Organ → Organ system → Organism
Rationale: Cells are the basic unit of life, which group into tissues. Tissues form organ
s, organs form organ systems, and organ systems compose an organism. This hierarch
ical organization is foundational in anatomy.
Q3. Homeostasis is best defined as:
a) The ability to grow and develop
b) Maintaining a stable internal environment despite external changes
c) The ability to respond to external stimuli
d) The process of cell division
Answer: b) Maintaining a stable internal environment despite external changes
Rationale: Homeostasis maintains internal stability
(e.g., temperature, pH, glucose) despite fluctuations in the external environment. It is
essential for survival and proper function of organ systems.

, Q4. Which of the following is NOT considered a necessary life function?
a) Responsiveness
b) Reproduction
c) Movement
d) Telepathy
Answer: d) Telepathy
Rationale: Essential life functions include responsiveness, reproduction, movement, g
rowth, metabolism, and homeostasis. Telepathy is not a biological function.
Q5. Negative feedback mechanisms in the body:
a) Enhance deviations from the normal state
b) Reverse deviations from the normal state
c) Maintain a constant deviation
d) Only occur in the endocrine system
Answer: b) Reverse deviations from the normal state
Rationale: Negative feedback counteracts changes to maintain homeostasis. For exa
mple, when body temperature rises, mechanisms like sweating and vasodilation reduc
e it to normal levels.
Q6. Which of the following is an example of positive feedback?
a) Blood glucose regulation
b) Blood clotting
c) Body temperature regulation
d) Osmoregulation
Answer: b) Blood clotting
Rationale: Positive feedback amplifies a response. In blood clotting, platelets release
chemicals that attract more platelets until the wound is sealed, rather than restoring b
alance.
