Questions with Rationales
SECTION 1: SCIENCE (100 Questions)
Human Anatomy & Physiology (Questions 1-40)
1. Which of the following correctly traces the path of blood from the right ventricle
to the left atrium?
A) Right ventricle → pulmonary artery → lungs → pulmonary vein → left atrium
B) Right ventricle → aorta → lungs → pulmonary artery → left atrium
C) Right ventricle → pulmonary vein → lungs → pulmonary artery → left atrium
D) Right ventricle → left atrium → lungs → pulmonary artery
Answer: A
Rationale: Blood flows from the right ventricle through the pulmonary artery to the lungs
for oxygenation, then returns via the pulmonary veins to the left atrium. This is the
pulmonary circulation pathway.
2. The sinoatrial (SA) node is best described as the:
, Page 2 of 139
A) Valve between the right atrium and right ventricle
B) Pacemaker of the heart
C) Structure that conducts impulses to the ventricles
D) Wall separating the right and left sides of the heart
Answer: B
Rationale: The SA node is the heart's natural pacemaker, located in the right atrium. It
generates electrical impulses that initiate each heartbeat.
3. Which blood type is considered the universal donor?
A) Type A
B) Type B
C) Type AB
D) Type O
Answer: D
Rationale: Type O blood lacks A and B antigens on red blood cells, so it will not trigger an
immune response in recipients with other blood types. Type AB is the universal
recipient.
4. Where does gas exchange occur in the respiratory system?
A) Trachea
B) Bronchi
C) Alveoli
D) Bronchioles
Answer: C
Rationale: Alveoli are tiny air sacs where gas exchange occurs—oxygen diffuses into the
blood, and carbon dioxide diffuses out. This is one of the most frequently tested
concepts on the TEAS.

5. Which structure prevents food from entering the trachea during swallowing?
A) Epiglottis
B) Pharynx
C) Larynx
D) Esophagus
Answer: A
Rationale: The epiglottis is a flap of cartilage that covers the trachea during swallowing
to prevent aspiration of food or liquid into the lungs.
6. During inhalation, the diaphragm:
A) Relaxes and moves upward
B) Contracts and moves downward
C) Remains stationary
D) Contracts and moves upward
Answer: B
Rationale: During inhalation, the diaphragm contracts and flattens, moving downward to
increase thoracic volume and decrease pressure, drawing air into the lungs.
7. Which enzyme, secreted by the stomach, begins the digestion of proteins?
A) Amylase
B) Pepsin
C) Lipase
D) Trypsin
Answer: B
, Page 4 of 139
Rationale: Pepsin is activated by hydrochloric acid in the stomach and begins protein
digestion. Amylase breaks down carbohydrates, and lipase digests fats.
8. Where does the majority of nutrient absorption occur?
A) Stomach
B) Large intestine
C) Small intestine
D) Esophagus
Answer: C
Rationale: The small intestine is the primary site of nutrient absorption, aided by villi and
microvilli that provide a large surface area for absorption.
9. Which accessory organ produces bile to aid in fat digestion?
A) Pancreas
B) Gallbladder
C) Liver
D) Spleen
Answer: C
Rationale: The liver produces bile. The gallbladder stores and concentrates bile, but the
liver is the organ that produces it.
10. Which of the following are functions of the urinary system? (Select all that
apply.)
A) Kidney helps regulate water balance
B) Regulates levels of electrolytes such as sodium and potassium
C) Eliminates metabolic waste
D) Produces digestive enzymes
