The left ventricle has a more muscular wall than the other three chambers of the heart because the left ventricle: A) houses the pacemaker of the heart. B) must generate enough force and blood pressure to pump blood into the aorta. C) must decrease the amount of pressure on the blood so it can flow more smoothly through the atria. D) pumps blood more slowly than the other chambers. E) receives blood directly from major arteries.

B) must generate enough force and blood pressure to pump blood into the aorta. 

IT is the perfect answer


  • as we know that the aorta is the largest artery among our blood vessels. since it is an artery it has thick walls to counter the pressure exerted by the coming blood on its wall.
  • aorta is the main and common artery to pave blood to our whole body. So, as it has to transport blood to the whole body it needs a preferable and the most suitable magnitude of force of blood so, that it could be easily transferred to our whole body 
  • and hence to generate such huge amount of force huge amount of muscle fibre from muscles os needed which is owned by our heart's left ventricle.

agree to post#1 The answer is B because the left venticle has to pump blood to the aorta and thus it needs to be more muscular to attain greater force.
