A&P 102 Final Exam – Ivy Tech 150-Question Practice
Exam with
Correct -detailed100%ANSWERs & Detailed
Rationales
(Cardiovascular • Respiratory • Digestive • Urinary •
Reproductive •
Endocrine Systems)
1. Which chamber of the heart has the thickest wall?
A. Right atrium
B. Left atrium
C. Right ventricle
D. Left ventricle
Correct -detailed100%ANSWER: D. Left ventricle
Rationale:👀*** It pumps blood to the entire body and requires the
most force.
2. The mitral valve is located between the:
A. Right atrium and right ventricle
B. Left atrium and left ventricle
C. Left ventricle and aorta
D. Right ventricle and pulmonary trunk
Correct -detailed100%ANSWER: B. Left atrium and left
ventricle
Rationale:👀*** The mitral (bicuspid) valve prevents backflow into
the left atrium.
,3. Which blood vessel carries oxygenated blood away from
the heart?
A. Vein
B. Capillary
C. Artery
D. Venule
Correct -detailed100%ANSWER: C. Artery
Rationale:👀*** Arteries carry blood away from the heart (usually
oxygenated).
4. The pulmonary circulation carries blood between the:
A. Heart and body tissues
B. Heart and kidneys
C. Heart and lungs
D. Lungs and brain
Correct -detailed100%ANSWER: C. Heart and lungs
Rationale:👀*** Pulmonary circulation allows gas exchange in the
lungs.
5. Which part of an ECG represents ventricular
depolarization?
A. P wave
B. QRS complex
C. T wave
,D. PR interval
Correct -detailed100%ANSWER: B. QRS complex
Rationale:👀*** Ventricular depolarization triggers ventricular
contraction.
6. Which blood pressure reading represents systolic
pressure?
A. Bottom number
B. Mean arterial pressure
C. Pressure during ventricular relaxation
D. Pressure during ventricular contraction
Correct -detailed100%ANSWER: D. Pressure during
ventricular contraction Rationale:👀*** Systolic pressure occurs
when ventricles contract.
7. Which hormone increases heart rate and blood pressure
during stress?
A. Insulin
B. Aldosterone
C. Epinephrine
D. ADH
Correct -detailed100%ANSWER: C. Epinephrine
Rationale:👀*** Epinephrine activates the sympathetic nervous
system.
, 8. Which plasma protein is most abundant?
A. Fibrinogen
B. Globulin
C. Albumin
D. Hemoglobin
Correct -detailed100%ANSWER: C. Albumin
Rationale:👀*** Albumin maintains osmotic pressure and
transports substances.
9. Hemoglobin’s primary function is to:
A. Transport nutrients
B. Fight infection
C. Carry oxygen
D. Regulate pH
Correct -detailed100%ANSWER: C. Carry oxygen
Rationale:👀*** Hemoglobin binds oxygen in red blood cells.
10. Which white blood cell is most abundant?
A. Lymphocyte
B. Monocyte
C. Eosinophil
D. Neutrophil
Correct -detailed100%ANSWER: D. Neutrophil
Rationale:👀*** Neutrophils are the body’s first responders to
infection.
