Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the strongest (thickest) part of the heart?
A
right atrium
B
right ventricle
C
left ventricle
D
left atrium
Explanation: 

Detailed explanation-1: -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-2: -The left ventricle is the main powerhouse of the heart, having to pump blood all the way around the systemic circulation. Because of this it has the largest, most muscular walls of any of the chambers. In fact, it is three times as thick as the right ventricle.

Detailed explanation-3: -The left ventricle is the largest and strongest chamber in your heart. The left ventricle’s chamber walls are only about 1.0 to 1.3cm, but they have enough force to push blood through the aortic valve and into your body.

Detailed explanation-4: -The myocardium is thickest in the left ventricle, as this chamber must create substantial pressure to pump blood into the aorta and throughout systemic circulation.

Detailed explanation-5: -The left ventricle pumps blood to all parts of the body, while the right ventricle only pumps blood to the lungs. Therefore, the wall of the left ventricle is thicker than the right ventricle.
