What is connected to the right ventricle via the papillary muscle and the string-like chordae tendonae?
  1. Bicuspid valve
  2. Tricuspid valve
  3. Cuspid valve
  4. Bypass valve
Explanation
Answer - B - The tricuspid valve is connected to the right ventricle via the papillary muscle and the string-like chordae tendonae. The tricuspid valve separates the right atrium and right ventricle. Anatomically speaking, the pulmonic valve and aortic valve function directly off of directional blood flow and do not utilize the chordae tendonae and the papillary muscle structures.
