Question 1

Which structures form the boundaries of the inferior thoracic aperture?

  • The 12th rib, a vertebra, the costal margin, and the xiphoid process
  • The first rib, a vertebra, and the manubrium
  • The sternum, clavicle, and first rib
  • The thoracic aorta, coronary sinus, and diaphragm
Question 2

What is the origin of the posterior intercostal arteries?

  • The thoracic aorta
  • The internal thoracic artery
  • The musculophrenic artery
  • The inferior phrenic artery
Question 3

The anterior intercostal arteries arise from the thoracic aorta.

  • True
  • False
Question 4

Which nerve innervates the diaphragm?

  • The phrenic nerve (C3–C5)
  • The intercostal nerves
  • The vagus nerve
  • The sympathetic chain
Question 5

Which part of the heart forms its apex?

  • The inferolateral part of the left ventricle
  • The right ventricle
  • The right atrium
  • The left atrium
Question 6

What makes up the right pulmonary surface of the heart?

  • The right atrium
  • The left ventricle
  • The left atrium
  • The right ventricle
Question 7

The pericardial cavity lies between the visceral and parietal serous pericardium and permits relatively unrestricted movement of the heart.

  • True
  • False
Question 8

Which structures are contained in the coronary sulcus?

  • The right coronary artery, circumflex branch of the left coronary artery, small cardiac vein, and coronary sinus
  • The anterior interventricular artery and great cardiac vein
  • The posterior interventricular artery and middle cardiac vein
  • The phrenic nerve, vagus nerve, and sympathetic chain
Question 9

Which three vessels return blood to the right atrium?

  • The superior vena cava, inferior vena cava, and coronary sinus
  • The superior vena cava, inferior vena cava, and pulmonary veins
  • The aorta, pulmonary trunk, and coronary sinus
  • The internal thoracic artery, musculophrenic artery, and inferior phrenic artery
Question 10

What is a key function of the cardiac skeleton?

  • It maintains the integrity of the openings it surrounds and provides attachment for the cusps and myocardium.
  • It secretes lubricating fluid into the pericardial cavity.
  • It forms the apex of the heart.
  • It attaches the fibrous pericardium to the posterior surface of the sternum.
Question 11

Blood passes from the right atrium into the right ventricle through the _____, which is guarded by the tricuspid valve.

Fill in the blank

Question 12

What happens if a thrombus in the left ventricle dislodges?

  • It becomes an embolism and can cause a stroke if it reaches the brain.
  • It becomes pericardial effusion and causes biventricular failure.
  • It travels to the right atrium through the coronary sinus.
  • It remains in the left ventricle and ruptures the cardiac skeleton.
Question 13

What is the infundibulum?

  • The outflow tract of the right ventricle
  • The inflow tract of the right atrium
  • The thick part of the interventricular septum
  • The valve between the left atrium and left ventricle
Question 14

The infundibulum is the outflow tract of the left ventricle.

  • True
  • False
Question 15

Which part of the interventricular septum is thick and forms the major part of the septum?

  • The muscular part
  • The membranous part
  • The infundibulum
  • The papillary muscle
Question 16

The thin upper part of the interventricular septum is called the ______ part.

Fill in the blank

Question 17

What do the papillary muscles attached to the atrioventricular valves do?

  • They contract with the ventricle and prevent the valves from everting into the atrium.
  • They open the atrioventricular valves during ventricular contraction.
  • They close the semilunar valves during atrial contraction.
  • They form the thin upper part of the interventricular septum.
Question 18

Papillary muscles help prevent atrioventricular valves from everting into the atria when intraventricular pressure increases.

  • True
  • False
Question 19

What is valve stenosis?

  • A calcified valve that cannot open fully
  • A valve that opens more widely than normal
  • A valve that has no papillary muscles attached
  • A thin upper part of the interventricular septum
Question 20

Which effect can result from valve stenosis?

  • Decreased oxygen supply
  • Increased oxygen supply
  • Reduced workload for the heart
  • Full opening of the calcified valve
Question 21

Calcification that prevents a valve from opening fully is called valve ______.

Fill in the blank

Question 22

Which is listed as a clinical outcome of mitral valve stenosis and/or incompetence?

  • Left ventricular hypertrophy
  • Right ventricular atrophy
  • Pericardial effusion
  • Aortic dissection
Question 23

Which pulmonary consequence is associated with mitral valve stenosis and/or incompetence?

  • Increased pulmonary venous pressure and pulmonary edema
  • Decreased pulmonary venous pressure
  • Pulmonary fibrosis
  • Pneumothorax
Question 24

Mitral valve stenosis and/or incompetence can lead to enlargement and hypertrophy of the left atrium.

  • True
  • False
