Question

Which term is synonymous with the mitral valve?

Answers

  1. Aortic valve
    • Rationale:

      The aortic valve is not synonymous with the mitral valve as both have different functions within the heart.

  2. Bicuspid valve
    • Rationale:

      Another term for the mitral valve is the bicuspid valve. This is another term for this valve as it has two cusps.

  3. Tricuspid valve
    • Rationale:

      The tricuspid valve has three, not two, cusps; therefore, it is not synonymous with the mitral valve.

  4. Pulmonic valve
    • Rationale:

      The pulmonic valve is not synonymous with the mitral valve as each has different functions within the heart muscle.

Overview

A heart valve is a one-way structure that allows blood to flow in only one direction through the heart.

Explanation

Learning Outcomes

There are four valves in the human heart that determine the pathway of blood flow. The four valves are as follows: aortic, mitral, pulmonic, and tricuspid. The mitral valve allows blood to flow from the left atrium into the left ventricle. The mitral valve has two flaps (cusps); therefore, it is also referred to as the bicuspid valve.
