IVY TECH APHY 101 FINAL EXAM QUESTIONS AND ANSWERS 2026
1. Which of the following best describes the reaction NaNO3 + HCl → HNO3 + NaCl?
A. Synthesis reaction
B. Decomposition reaction
C. Exchange reaction
D. Combustion reaction
Answer: C. Exchange reaction
Rationale: In this reaction, the cations and anions of two compounds switch places.
NaNO3 exchanges its Na⁺ with H⁺ from HCl to form HNO3 and NaCl, which is
characteristic of an exchange reaction.
2. The function of the association area in the frontal lobe is:
A. Regulating heart rate
B. Controlling voluntary movement
C. Higher intellectual processes, such as reasoning and judgment
D. Processing visual input
Answer: C. Higher intellectual processes, such as reasoning and judgment
Rationale: Association areas integrate information from multiple regions of the brain.
In the frontal lobe, they are responsible for complex cognition, planning, decision-
making, and personality expression.
3. Cerebrospinal fluid (CSF) is produced by ______ and its function is ______.
A. Choroid plexuses in the ventricles; protects the brain from blows to the skull
B. Hypothalamus; controls body temperature
C. Pineal gland; regulates sleep cycles
D. Medulla oblongata; controls heart rate
Answer: A. Choroid plexuses in the ventricles; protects the brain from blows
to the skull
Rationale: CSF is secreted by the choroid plexuses, which are specialized networks of
capillaries in the ventricles. It cushions the brain, maintains chemical stability, and
removes metabolic waste.
,4. The anaerobic reactions of cellular respiration occur in the ______, whereas the
aerobic reactions occur in the ______.
A. Nucleus; mitochondria
B. Cytoplasm without O2 required; mitochondria with O2 required
C. Ribosome; endoplasmic reticulum
D. Golgi apparatus; lysosomes
Answer: B. Cytoplasm without O2 required; mitochondria with O2 required
Rationale: Glycolysis (anaerobic) occurs in the cytoplasm and does not require
oxygen. The Krebs cycle and electron transport chain (aerobic) occur in the
mitochondria and require oxygen to generate ATP efficiently.
5. A pole vaulter keeps track of his position in mid-air through:
A. Photoreceptors
B. Mechanoreceptors
C. Proprioceptors
D. Nociceptors
Answer: C. Proprioceptors
Rationale: Proprioceptors provide feedback on the position and movement of the
body in space, allowing athletes like pole vaulters to maintain balance and
coordination mid-air.
6. Epithelial tissue functions in:
A. Conduction of nerve impulses
B. Support and structure
C. Secretion, absorption, and protection
D. Storage of fat
Answer: C. Secretion, absorption, and protection
Rationale: Epithelial tissue lines surfaces and cavities, forming barriers. It specializes
in absorbing nutrients, secreting substances like enzymes and mucus, and protecting
underlying tissues from mechanical and chemical damage.
7. Receptors for the special senses are found:
A. Primarily in the skin
B. Primarily in the head
C. In bones
D. Throughout the digestive tract
Answer: B. Primarily in the head
Rationale: Special senses—vision, hearing, taste, smell, and equilibrium—have
receptors concentrated in the head to process complex sensory information efficiently.
8. Which of the following lists the parts of a reflex arc in the correct sequence?
A. Receptor, motor neuron, interneuron, sensory neuron, effector
B. Receptor, sensory neuron, interneuron, motor neuron, effector
C. Sensory neuron, receptor, interneuron, motor neuron, effector
D. Effector, receptor, sensory neuron, interneuron, motor neuron
Answer: B. Receptor, sensory neuron, interneuron, motor neuron, effector
Rationale: A reflex arc is the pathway through which a reflex action occurs. The
, correct order is receptor → sensory neuron → interneuron → motor neuron → effector,
ensuring rapid, automatic responses.
9. Epidermis is ______, whereas dermis is ______.
A. Composed of connective tissue; composed of epithelial tissue
B. Composed of stratified squamous epithelial tissue; composed of connective tissue,
smooth muscle, and nerve cell processes
C. Vascular; avascular
D. Thick; thin
Answer: B. Composed of stratified squamous epithelial tissue; composed of
connective tissue, smooth muscle, and nerve cell processes
Rationale: The epidermis is primarily stratified squamous epithelium, which provides
a protective barrier. The dermis contains connective tissue, blood vessels, smooth
muscle, and nerve fibers, supporting structure, sensation, and thermoregulation.
10. Cartilage tissues are likely to be slow in healing following an injury because:
A. They lack nerve endings
B. They lack direct blood supplies
C. They are very flexible
D. They are covered by epithelial tissue
Answer: B. They lack direct blood supplies
Rationale: Cartilage is avascular, so nutrients and waste must diffuse through the
matrix, making repair and regeneration slow compared to vascularized tissues.
11. Most of the joints between the short bones in the ankle and wrist are:
A. Hinge joints
B. Pivot joints
C. Plane joints
D. Ball-and-socket joints
Answer: C. Plane joints
Rationale: Plane joints allow gliding movements between flat bone surfaces. The
carpals and tarsals primarily form plane joints, permitting limited movement and
flexibility in the wrist and ankle.
12. The muscular system is responsible for body movements, maintenance of posture,
and production of body heat.
A. True
B. False
Answer: A. True
Rationale: Muscles contract to generate movement, stabilize body position, and
produce heat as a byproduct of metabolism, which helps maintain homeostasis.
13. Chemistry deals with:
A. The composition and changes of substances that make up living and non-living
matter
B. Only living organisms
C. Only minerals and rocks
