IVY TECH APHY 101 MIDTERM EXAM QUESTIONS COMPLETE WITH
VERIFIED ANSWERS AND DETAILED EXPLANATIONS
1. What is the difference between anatomy and physiology?
A) Anatomy studies function; physiology studies structure
B) Anatomy studies structure; physiology studies function
C) Anatomy studies cells; physiology studies organs
D) Anatomy studies diseases; physiology studies treatments
Correct answer: B
Rationale: Anatomy is the study of the structure of body parts and their
relationships to one another. Physiology is the study of the function of body
parts—how they work and carry out life-sustaining activities .
2. Which of the following represents the correct order of the levels of organization
from simplest to most complex?
A) Cell, tissue, organelle, organ, organ system, organism
B) Organelle, cell, tissue, organ, organ system, organism
C) Organelle, tissue, cell, organ, organ system, organism
D) Cell, organelle, tissue, organ, organ system, organism
Correct answer: B
Rationale: The levels of organization from simplest to most complex are:
organelle → cell → tissue → organ → organ system → organism. Organelles are
the smallest functional units within cells, cells form tissues, tissues form organs,
organs work together in organ systems, and organ systems make up the
organism .
,3. A group of similar cells that work together to perform a specific function is
called a(n):
A) Organelle
B) Organ
C) Tissue
D) Organ system
Correct answer: C
Rationale: Tissues are groups of similar cells organized to perform a specific
function. Organs are collections of tissues, organelles are structures within cells,
and organ systems are groups of organs .
4. The maintenance of a stable internal environment despite changes in the
external environment is called:
A) Metabolism
B) Homeostasis
C) Anabolism
D) Catabolism
Correct answer: B
Rationale: Homeostasis is the body's ability to maintain a relatively stable internal
environment even when external conditions change. It is essential for survival and
proper functioning of cells and organs .
5. Which of the following is a requirement of life?
A) Carbon dioxide
B) Nitrogen gas
C) Water
D) Sunlight
Correct answer: C
,Rationale: The requirements of life include water, food, oxygen, heat, and
pressure. Water is needed to transport substances and regulate body
temperature. Food provides energy and building materials. Oxygen helps release
energy from food .
6. Which of the following is a characteristic of life?
A) Inactivity
B) Responsiveness to the environment
C) Isolation from surroundings
D) Constant internal conditions without change
Correct answer: B
Rationale: Characteristics of life include responsiveness to the environment
(reaction to internal or external changes), growth, reproduction, movement,
respiration, digestion, absorption, circulation, assimilation, and excretion .
7. A structure that carries out a specialized function within a cell is called a(n):
A) Tissue
B) Organ
C) Organelle
D) Organ system
Correct answer: C
Rationale: Organelles are specialized structures within cells that carry out
specific functions. Examples include mitochondria (energy production),
ribosomes (protein synthesis), and the nucleus (contains genetic material) .
8. The activities of an anatomist consist of __________, whereas those of a
physiologist consist of __________.
, A) Observing body parts; studying functions of body parts
B) Studying functions; observing body parts
C) Treating diseases; diagnosing conditions
D) Measuring vital signs; analyzing blood samples
Correct answer: A
Rationale: Anatomists focus on observing and describing body structures
(morphology). Physiologists focus on studying how those structures function
and work together .
9. Which of the following diseases would originate in the abdominopelvic cavity?
A) Pneumonia
B) Pancreatitis
C) Encephalitis
D) Pericarditis
Correct answer: B
Rationale: The abdominopelvic cavity contains the digestive organs, kidneys,
pancreas, and reproductive organs. Pancreatitis is inflammation of the pancreas,
which is located in the abdominopelvic cavity .
10. Which of the following best describes negative feedback?
A) A mechanism that amplifies a change away from the set point
B) A mechanism that reverses a change to return to the set point
C) A mechanism that has no effect on homeostasis
D) A mechanism that only occurs in disease states
Correct answer: B
Rationale: Negative feedback is a self-regulating mechanism that reverses a
change to return the body to its set point (homeostasis). Examples include body
