Correct answer: A. Left atrium and left ventricle

  • A. Left atrium and left ventricle
  • B. Right atrium and left ventricle
  • C. Left atrium and right ventricle
  • D. Right ventricle and right ventricle

Explanation

A bicuspid valve has only two leaflets (flaps or cusps), instead of three. Normally, the mitral valve is theonly bicuspid valve, and this is situated between the heart's left atrium and left ventricle. It ensures the flow of oxygenated blood from the left atrium to the left ventricle and prevents backflow during ventricular contraction.The tricuspid valve has three leaflets or cusps and is on the right side of the heart. It isbetween the right atrium and the right ventricle, and stops the backflow of blood betweenthe two.
