Inside the left venticle, the aortic vestibule is the smooth-walled, superior region that leads to the aorta. It is similar to the conus arteriosus in the right ventricle. Describe another structural similarity between the two ventricles.

Respuesta :

Iqta

Answer:

Presence of papillary muscles

Explanation:

  • Papillary muscles are structural components of the ventricles.
  • They are attached to the cusps of the mitral and tricuspid valves through connective tissue strings known as the cordinae tendeneae (heart strings).
  • These muscles prevent the prolaspse of these valves during ventricular systole.
  • Although they differ in number i.e. two in left and three in right ventricle, papillary muscles are present in both ventricles.
