Which portion of the heart is the most muscular?
A
Right Ventricle
B
Right Atrium
C
Left Ventricle
D
Left Atrium
Explanation: 

Detailed explanation-1: -A typical heart has two upper and two lower chambers. The upper chambers, the right and left atria, receive incoming blood. The lower chambers, the more muscular right and left ventricles, pump blood out of the heart.

Detailed explanation-2: -The left ventricle has the thickest wall out of all the chambers. The left ventricle is responsible for pumping the blood towards the tissues of the heart. This is why more muscles contracting inside the left ventricle helps produce a higher force to move the blood towards the system.

Detailed explanation-3: -The left ventricle is the largest and strongest chamber in your heart. The left ventricle’s chamber walls are only about a half-inch thick, but they have enough force to push blood through the aortic valve and into your body.

Detailed explanation-4: -Why is the left ventricular wall of the heart thicker than the right ventricular wall? To accommodate a greater volume of blood. To expand the thoracic cage during diastole. To pump blood with greater pressure.
