HLTH 222
Applied Human A & P II
Midterms Exam Review (Qns & Ans)
2025
1. Which of the following hormones is primarily responsible for
regulating serum calcium levels in the blood?
a) Insulin
b) Parathyroid hormone
c) Cortisol
d) Aldosterone
ANS: b) Parathyroid hormone
Rationale: Parathyroid hormone increases blood calcium levels
by stimulating osteoclasts to break down bone, increasing kidney
reabsorption of calcium, and facilitating vitamin D activation.

,2. The functional unit of the kidney responsible for the filtration
and reabsorption processes is called the:
a) Alveolus
b) Nephron
c) Hepatocyte
d) Neuron
ANS: b) Nephron
Rationale: The nephron is the structural and functional unit of
the kidney, consisting of the glomerulus and renal tubules
involved in filtering blood and forming urine.
3. Which part of the brain is primarily involved in coordinating
voluntary movements and maintaining balance?
a) Cerebrum
b) Cerebellum
c) Medulla oblongata
d) Hypothalamus
ANS: b) Cerebellum
Rationale: The cerebellum coordinates voluntary movements,
maintains balance and posture, and integrates sensory information
regarding the position of body parts.

, 4. Which type of muscle tissue is characterized by striations and
voluntary control?
a) Smooth muscle
b) Cardiac muscle
c) Skeletal muscle
d) Epithelial tissue
ANS: c) Skeletal muscle
Rationale: Skeletal muscle is striated and under voluntary
control, allowing for deliberate body movements.
5. Which blood vessel type typically carries oxygenated blood
away from the heart to the body, except for one major exception?
a) Veins
b) Capillaries
c) Lymphatics
d) Arteries
ANS: d) Arteries
Rationale: Arteries usually carry oxygenated blood except for
the pulmonary arteries, which carry deoxygenated blood from the
heart to the lungs.
