Q1.

A cutaway heart diagram uses labels P, Q, R and S. P lies between the chamber receiving the venae cavae and the ventricle below it. Q lies at the outlet of that ventricle. R lies between the chamber receiving the pulmonary veins and the thick-walled ventricle below it. S lies at the outlet of the thick-walled ventricle. Which labels identify the atrioventricular valves?

  1. A) R and S
  2. B) P and Q
  3. C) P and R
  4. D) Q and S

Q2.

A heart diagram has been rotated through half a turn, so its usual top and bottom positions are reversed. Label A is between the right atrium and right ventricle, B is where blood leaves the right ventricle, C is between the left atrium and left ventricle, and D is where blood leaves the left ventricle. Which labels identify the semilunar valves?

  1. A) C and D
  2. B) A and C
  3. C) B and D
  4. D) A and B

Q3.

In a longitudinal section of a mammalian heart, label X points to three pocket-shaped cusps between the right ventricle and a vessel leading to the lungs. Label Y points to three pocket-shaped cusps between the left ventricle and a vessel that supplies the body. How should X and Y be identified?

  1. A) X is the tricuspid valve, and Y is the mitral valve.
  2. B) X is the mitral valve, and Y is the tricuspid valve.
  3. C) X is the aortic semilunar valve, and Y is the pulmonary semilunar valve.
  4. D) X is the pulmonary semilunar valve, and Y is the aortic semilunar valve.

Q4.

A detailed heart section contains four labels. H and K point to valves whose flaps are attached to chordae tendineae. J and L point to pocket-like valves with no chordae tendineae at the exits of the ventricles. Which labels identify the semilunar valves?

  1. A) J and L
  2. B) K and L
  3. C) H and K
  4. D) H and J

Q5.

A schematic represents blood flow as: venae cavae → right atrium → V → right ventricle → W → pulmonary artery → lungs → pulmonary veins → left atrium → X → left ventricle → Y → aorta. Which option correctly identifies W and X?

  1. A) W is the tricuspid valve, and X is the aortic semilunar valve.
  2. B) W is the pulmonary semilunar valve, and X is the mitral valve.
  3. C) W is the aortic semilunar valve, and X is the tricuspid valve.
  4. D) W is the mitral valve, and X is the pulmonary semilunar valve.

Q6.

A mirrored heart diagram shows four labelled valves. A is between a chamber receiving the venae cavae and a thin-walled ventricle. B is at that ventricle's outlet. C is between a chamber receiving pulmonary veins and the ventricle with the thickest wall. D is at the outlet of the thickest-walled ventricle. Which label identifies the mitral valve?

  1. A) Label B
  2. B) Label D
  3. C) Label A
  4. D) Label C

Q7.

In a section through the heart, label M marks a three-flapped valve beside the chamber receiving the venae cavae. Label N marks a pocket-shaped valve leading into the pulmonary artery. Label O marks a two-flapped valve beside the chamber receiving pulmonary veins. Label P marks a pocket-shaped valve leading into the aorta. Which label identifies the tricuspid valve?

  1. A) Label N
  2. B) Label M
  3. C) Label P
  4. D) Label O

Q8.

The figure shows a frontal cutaway of a mammalian heart. Which label identifies the pulmonary semilunar valve?

Diagram for question 8: The figure shows a frontal cutaway of a mammalian heart. Which label identifies the pulmonary semilunar valve?
  1. A) Label G
  2. B) Label F
  3. C) Label E
  4. D) Label H
