BIOLOGY - HEART STRUCTURE

Heart Anatomy Quiz

  • Focuses on identifying heart valves in diagrams and images
  • Covers the anatomy of the heart's chambers and valves
  • Emphasizes understanding of blood flow through the heart
  • Designed for Grade 9 students with a challenging difficulty level

Here are the first 3 questions. Click “View all questions” to see the complete assessment.

Q1.

A cutaway heart diagram marks valve X between an upper chamber that receives the venae cavae and a lower chamber that pumps blood towards the lungs. Which valve is X?

  1. A) Aortic semilunar valve
  2. B) Bicuspid (mitral) valve
  3. C) Tricuspid valve
  4. D) Pulmonary semilunar valve

Q2.

In a labelled heart schematic, L lies between the left atrium and left ventricle, M lies where blood leaves the left ventricle, N lies between the right atrium and right ventricle, and P lies where blood leaves the right ventricle. Which labels identify the semilunar valves?

  1. A) L and M
  2. B) N and P
  3. C) M and P
  4. D) L and N

Q3.

A heart diagram uses arrow A for the valve at the entrance to the artery that forms the aortic arch. Arrow B points to the valve between the right atrium and right ventricle. Which identification is correct?

  1. A) A is the bicuspid valve; B is the pulmonary semilunar valve
  2. B) A is the pulmonary semilunar valve; B is the bicuspid valve
  3. C) A is the aortic semilunar valve; B is the tricuspid valve
  4. D) A is the tricuspid valve; B is the aortic semilunar valve

Q4.

A heart image has been rotated, so page position cannot be used to identify the sides. Label R points to the valve between the chamber receiving pulmonary veins and the ventricle with the thickest muscular wall. Which valve is R?

  1. A) Bicuspid (mitral) valve
  2. B) Aortic semilunar valve
  3. C) Pulmonary semilunar valve
  4. D) Tricuspid valve

Q5.

A flow diagram through the right side of a mammalian heart shows: vena cava → right atrium → valve T → right ventricle → valve U → pulmonary artery. How should T and U be identified?

  1. A) T is the bicuspid valve; U is the aortic semilunar valve
  2. B) T is the aortic semilunar valve; U is the bicuspid valve
  3. C) T is the tricuspid valve; U is the pulmonary semilunar valve
  4. D) T is the pulmonary semilunar valve; U is the tricuspid valve

Q6.

On a transparent heart overlay, label K points to pocket-shaped cusps with no chordae tendineae. They are located at the base of the vessel arising from the left ventricle and supplying the systemic circulation. What does K identify?

  1. A) Bicuspid (mitral) valve
  2. B) Pulmonary semilunar valve
  3. C) Tricuspid valve
  4. D) Aortic semilunar valve

Q7.

In a sectional heart drawing, Y points to cusps attached to chordae tendineae between an atrium and a ventricle. Z points to pocket-shaped cusps without chordae at the opening from a ventricle into an artery. Which classification is correct?

  1. A) Both Y and Z are atrioventricular
  2. B) Both Y and Z are semilunar
  3. C) Y is semilunar; Z is atrioventricular
  4. D) Y is atrioventricular; Z is semilunar

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