BIOL252 Human Anatomy & Physiology II w/Lab - Module 2 Exam Review
200 Practice Questions with Answers and Rationales
SECTION 1: CARDIAC ANATOMY (Questions 1-45)
1. Which layer of the heart wall is responsible for the contractile function of the
heart?
A) Epicardium
B) Myocardium
C) Endocardium
D) Pericardium
Answer: B) Myocardium
Rationale: The myocardium is the middle and thickest layer of the heart wall,
composed of cardiac muscle tissue responsible for the heart's pumping action.
,The epicardium is the outer layer, the endocardium lines the chambers, and the
pericardium is the protective sac surrounding the heart .
2. The heart is located in which anatomical region?
A) Pericardial cavity
B) Mediastinum
C) Pleural cavity
D) Abdominal cavity
Answer: B) Mediastinum
Rationale: The heart is positioned in the mediastinum, the central compartment
of the thoracic cavity between the lungs. It sits within the pericardial cavity, which
is a subdivision of the mediastinum .
,3. Which chamber of the heart receives deoxygenated blood from the superior
and inferior vena cavae?
A) Left atrium
B) Right atrium
C) Left ventricle
D) Right ventricle
Answer: B) Right atrium
Rationale: The right atrium receives deoxygenated blood returning from systemic
circulation via the superior and inferior vena cavae. The left atrium receives
oxygenated blood from the pulmonary veins .
4. The right ventricle pumps blood into which structure?
A) Aorta
, B) Pulmonary trunk
C) Pulmonary veins
D) Left ventricle
Answer: B) Pulmonary trunk
Rationale: The right ventricle pumps deoxygenated blood into the pulmonary
trunk, which splits into the left and right pulmonary arteries that carry blood to
the lungs for oxygenation .
5. Which heart chamber has the thickest muscular wall?
A) Right atrium
B) Left atrium
C) Right ventricle
