Module 2 Exam Review 70+ Questions and Answers –
Summary | Portage Learning
Question 1
Identify the component of the heart pointed to by the line.
A. Right atrium
B. ✅Tricuspid valve
C. Right ventricle
D. Inferior vena cava
Rationale:
The tricuspid valve lies between the right atrium and right ventricle and prevents backflow of
blood during ventricular contraction.
,ESTUDYR
Question 2
Identify the letter of the heart component described below:
Shallow depression that is a remnant of the foramen ovale.
A. A
B. C
C. D
D. ✅E
Rationale:
The fossa ovalis is a shallow depression in the interatrial septum and represents the closed
foramen ovale from fetal circulation.
Question 3
Identify the highlighted structure.
A. Papillary muscles
B. Trabeculae carneae
C. ✅Chordae tendineae
D. Interventricular septum
Rationale:
Chordae tendineae anchor atrioventricular valve cusps to papillary muscles, preventing valve
prolapse during systole.
✅ PAGE 2 – Internal Heart Structures (Sectioned View)
Image Prompt – Page 2
Detailed sectional diagram of the human heart showing atrioventricular valves, papillary
muscles, chordae tendineae, interventricular septum, and ventricular chambers. Emphasis on
valve mechanics during systole and diastole. Medical illustration style.
Question 4
Which structure prevents eversion of the AV valves during ventricular contraction?
, ESTUDYR
A. Trabeculae carneae
B. ✅ Papillary muscles
C. Interatrial septum
D. Coronary sinus
Rationale:
Papillary muscles contract to tighten chordae tendineae, stabilizing the AV valves during systole.
Question 5
Which chamber has the thickest myocardial wall?
A. Right atrium
B. Right ventricle
C. Left atrium
D. ✅Left ventricle
Rationale:
The left ventricle generates the highest pressure to pump blood through systemic circulation,
requiring a thicker wall.
Question 6
Blood flowing through the tricuspid valve moves from the:
A. Right ventricle to pulmonary trunk
B. Left atrium to left ventricle
C. ✅Right atrium to right ventricle
D. Inferior vena cava to right atrium
Rationale:
The tricuspid valve separates the right atrium from the right ventricle.
✅ PAGE 3 – Cardiac Septa & Surface Features
Image Prompt – Page 3
Labeled diagram of the heart highlighting the interatrial septum, interventricular septum, fossa
ovalis, coronary sulcus, and anterior interventricular sulcus. Clear lettered labels for
assessment-style identification.
