DAANCE Midterm Exam Questions and Verified
Answers with Rationale Latest Edition 2026/2027


Module 1: Basic Sciences (Anatomy and Physiology)
1. The heart is divided into how many chambers?
 A. Two
 B. Three
 C. Four
 D. Five
 Correct Answer: C
 Rationale: The human heart consists of four distinct
chambers: two upper chambers called atria and two
lower chambers called ventricles, which work
together to pump blood through the pulmonary and
systemic circulations.
2. Which blood vessel carries deoxygenated blood from
the right ventricle to the lungs?
 A. Aorta
 B. Pulmonary artery
 C. Pulmonary vein
 D. Superior vena cava
 Correct Answer: B
 Rationale: The pulmonary artery is unique because it
is the only artery in the adult body that carries

, deoxygenated blood away from the heart to the lungs
for gas exchange.
3. Normal resting blood pressure for a healthy adult is
generally defined as approximately:
 A. 140/90 mmHg
 B. 120/80 mmHg
 C. 100/60 mmHg
 D. 160/100 mmHg
 Correct Answer: B
 Rationale: Standard clinical guidelines define normal
adult resting blood pressure as less than 120/80
mmHg. Values consistently above 140/90 mmHg are
classified as hypertension.
4. The primary pacemaker of the normal heart is the:
 A. Atrioventricular node
 B. Bundle of His
 C. Sinoatrial node
 D. Purkinje fibers
 Correct Answer: C
 Rationale: The sinoatrial (SA) node is located in the
wall of the right atrium and spontaneously generates
electrical impulses that determine the normal rhythm
and rate of the heart.
5. Oxygen and carbon dioxide exchange takes place
primarily across the walls of the:

, A. Bronchi
 B. Trachea
 C. Alveoli
 D. Bronchioles
 Correct Answer: C
 Rationale: Alveoli are tiny, thin-walled air sacs at the
terminal ends of the respiratory tree where oxygen
diffuses into the pulmonary capillaries and carbon
dioxide diffuses out.
6. The cranial nerve that provides major sensory
innervation to the maxilla and mandibular regions of
the oral cavity is cranial nerve:
 A. V (Trigeminal)
 B. VII (Facial)
 C. IX (Glossopharyngeal)
 D. XII (Hypoglossal)
 Correct Answer: A
 Rationale: The trigeminal nerve (CN V) is the fifth
cranial nerve and is responsible for providing sensory
innervation to the face, teeth, oral cavity, and sinuses
via its ophthalmic, maxillary, and mandibular
divisions.
7. Which anatomical structure prevents food and liquids
from entering the larynx and trachea during
swallowing?

,  A. Uvula
 B. Epiglottis
 C. Soft palate
 D. Thyroid cartilage
 Correct Answer: B
 Rationale: The epiglottis is a flexible flap of cartilage
located behind the tongue that folds down over the
glottis during the act of swallowing to protect the
airway from aspiration.
8. The amount of air that is moved in and out of the
lungs with each normal, resting breath is called the:
 A. Vital capacity
 B. Residual volume
 C. Tidal volume
 D. Total lung capacity
 Correct Answer: C
 Rationale: Tidal volume refers to the standard
volume of air inspired and expired during normal,
quiet respiration, typically measuring around 500 mL
in a healthy adult.
9. Deoxygenated blood returns from the body tissues
and empties directly into which chamber of the heart?
 A. Left atrium
 B. Right atrium
 C. Left ventricle
