Rus_ich [418]

The wall of the left ventricle is thicker than that of the right - True

The left ventricle pumps more blood than the right - False

<u>Explanation:</u>

Heart has 4 number of chambers. One among these chambers is the left ventricle. Among the four cambers of the heart, the thick one is the left ventricle. It appears below the left atrium. The left ventricle is present in the bottom left part of the heart. When the contraction of heart occurs the blood from the valve called mitral enters the left atrium from the left atrium.  

The left ventricle transports the oxygenated blood to the human body. The left ventricle needs along these things for pumping the blood. The right ventricle can function by itself and is more powerful than left ventricle. The right ventricle is responsible in pumping blood to the lungs on its own.
